Tuned Mass Damper and Magnetorheological Attenuator Compared

There are plenty of damper solutions for attenuating unwelcome vibration. A magnetorheological damper and a tuned mass damper, for instance. Here we discuss the pros and cons of these two various actuators.

Tuned Mass Damper Pluses and Minuses

The concept of a tuned mass damper (TMD) is to somehow wisely respond to shake. A distinction I go along with is that a TMD creates a counteracting force by moving a weight at counter cycle with the base shake.

An advantage of a TMD is evidently its capability to generate a substantial difference by impacting a force to the shaking structure via a moving weight. This can also be one of its major down sides. In case you put on the force continuously at inappropriate moment, the vibration system can become instable if the motion of the tuned mass damper takes place in the resonance wavelength. And operation at the resonance frequency is quite typical, as the resonance frequency is many times the one being put to sleep.

Ok, the fact remains that with a semi-active actuator there’s also the possibility of messing with something at the resonance point by handling the damper improperly, but at least no supplementary force with a mobile mass is used and therefore the possible harm is not as dangerous.

A further problem is the higher quantity of moving components. A tuned mass damper is likewise the one that calls for the most hand-operated setup labor.

Semi-Active Damper Positives and Negatives

The functioning principle of a semi-active actuator is founded on the material properties. As for the magnetorheological actuator, the attenuating substance adjusts its viscosity. The substance is a ferrofluid: oil that contains metal particles. The theory is that any time you put on a magnetic field to the matter, the metal particles are aligned according to the field lines and produce the fluid stiff. This generates in practice an actuator which might be changed on and off in mere milliseconds.

A drawback of the attenuator is clearly its relatively low volume of use. This really is mainly due to the fact that it’s fairly fresh alternative available in the market and not very widely reviewed yet. Nevertheless, this is regularly changing since the scientific study material increases.

In my view the semi-active damper brings together the best components of the previous actuator categories:

Small dimensions

A small amount of moving elements

Responds real-time to a number of vibration wavelengths

Also, as a direct consequence of its small dimensions the magnetorheological actuator can be installed at the side of a present passive damper that is currently attenuating certain wavelengths. The magnetorheological damper will then concentrate on the vibration that can vary over time.

Do you want to know exactly how the magnetorheological attenuator outperforms the tuned mass damper? Have a look at Magnetorheological Damper Laboratory! If you do not undoubtedly need a tuned mass damper, I recommend a semi-active one.

Auto Repair: The Top Ten Mistakes Made By Your Mechanic

Number One:

Not confirming the concern. Confirming a repair concern is a basic diagnostic principle frequently overlooked. To fix a problem, the first thing one must do is recognize it.

Number Two:

Insufficient Road Testing. The importance of a thorough road test (even for an oil change) is well documented in automotive training manuals. Yet, many technicians consider driving the vehicle into the shop good enough.

Number Three:

Misdiagnosing. For the above reasons and a multitude of others, your vehicle is misdiagnosed more often than not. Mechanics will spend hours chasing the wrong problem, wasting your time and money.

Number Four:

Throwing parts at a problem. To compensate for lack of skills, mechanics often just throw parts at the problem in the hope of getting lucky. It’s common to hear mechanics say I replaced this, this, this, and that, and the problem’s still not fixed. This goes right back to mistake number one: confirm the problem with diagnostics, then proceed.

Number Five:

Not addressing primary concerns first. Technicians often spend an inordinate amount of time looking for easy sells that will fatten their paychecks. There’s nothing wrong with this provided there’s no charge for the inspection, it doesn’t conflict with your time, and the upsell suggestions are valid (they’re frequently not). However, this type of free inspection and the subsequent upselling too often overshadows the primary concern. So…what’s wrong with my car?

Number Six:

Overconfidence. Too often unqualified technicians get in over their heads. Rather than defer to a more experienced technician or facility, they often keep going and do more harm. How’s it go…The road to hell is paved with good intentions?

Number Seven:

Taking shortcuts. In the ongoing effort to beat the clock, technicians will create a host of problems: breaking parts, snapping bolts, short circuiting sensitive electronics. Refer to Auto Repair: How Can They Screw Up an Oil Change for a great discussion.

Number Eight:

Poor Repairs. Whether through incompetence or laziness, mechanics frequently don’t do repairs correctly. It’s often sloppy work. Forgotten bolts, parts not lined up correctly, or components not re-installed properly are common. It gets worse with computer repairs: incorrect software programming, coding, and resynchronization protocols are just a few.

Number Nine:

Not confirming repairs. After a repair is complete, it’s important to re-check to ensure that the problem is indeed fixed. Too often parts are thrown in and the car is pulled out only to pull in another victim.

Number Ten:

Making a mess. If the above nine mistakes weren’t bad enough, there are now greasy fingerprints on the hood and steering wheel, and two big greasy boot marks on the carpet.

Durham North Carolina Auto Repair – Making Sure You Get a Bargain

If you’ve lived in any one place for a long period of time, you most likely have a favorite auto repair place that you go to whenever you need help. Once you are familiar with the workers, you know that they charge a fair price and won’t bill you extra for unneeded services. You’ve had the opportunity to try a number of different auto repair places, and find out who you can trust to repair your car for a good price. But when you undergo car troubles while traveling, you don’t have the luxury of finding out which auto repair shop offers the best services. So if you are in need of Durham, North Carolina auto repair, it can be hard to choose one. Auto mechanics are notorious for charging ridiculous amounts of money for simple procedures, and unfortunately this stereotype is not unfounded. There are a few ways to find out which of the local options will be the best auto repair choice.

Since you aren’t able to utilize any past knowledge about Durham, North Carolina auto repair shops, you may consider consulting a few other people and see if they have a favorite place that they trust over any of the other local shops. If you are experiencing car troubles, you should stop at the nearest place (although you might not have much of a choice). Ask around for a good Durham, North Carolina auto repair shop, and find out where the local people go when they are having car troubles. That way you can be armed with the knowledge of which auto repair shop is trustworthy, without going through the painful process of being overcharged for car repairs that are very quick and simple. It won’t just save you money, but also time, and possibly the need to return to an auto repair shop in the future depending on the quality of the one you find.

Some local Durham, North Carolina auto repair shops may need to order a part to fix your car. If this is the unfortunate case, you may end up staying in Durham a little longer than you expected. If they need to order it directly from the factory, it may take several weeks. But don’t give up all hope yet. Before you commit to waiting for the part to ship, go around to some of the other local auto repair shops and see if they have the part you need in stock. It’s best to spend some time exploring your alternate options before you resign to staying in Durham for a longer time. Check out every specialized store you can to find the part you need, and perhaps you will get lucky enough to find it. The Durham Yellow Pages can help with this task.

In short, it is hard to ever be sure about how much you can trust an establishment that you are considering giving business to. But ask around and be prepared to deal with any problems that may arise during the repairing of your vehicle. Durham, North Carolina auto repair choices offer a number of very reliable organizations who will charge exactly what the repair is worth. But if you pick a random one to go to when you need repairs, it isn’t likely that you’ll encounter one of the trustworthy ones. So find out what the choices of the locals entail before you decide on a place to go, and you will have your car back in action in no time at all. And hopefully, your wallet won’t be too far depleted by the bill of the Durham, North Carolina auto repair shop.

Repair Your Credit With A Bad Credit Auto Loan

If you’re suffering with bad credit, poor credit, blemished or damaged credit, or have recently declared bankruptcy, you know it can be hard to get creditors to extend credit. It’s a myth however that you won’t qualify for credit after bankruptcy, or with a bad credit history. You can find secured loan products, and secured credit is the easiest route to rebuilding your credit history and improving your credit score.

What is secured debt? Secured debt is any form of credit that is backed by an asset, called “collateral”, the security for your loan. One example is a mortgage, which is secured by your home. The mortgage lender puts a lien on your home, and can foreclose if you do not pay the mortgage. The lender therefore is protected if you repeat your credit mistakes of the past and fail to pay.

Another example of a secured loan is a secured credit card. A secured credit card requires you to deposit a certain amount with the issuing bank, for example $300, and the issuing bank then gives you a credit card with a $300 credit limit. The bank has security if you don’t pay – they will simply keep your $300 deposit. There is no risk, and so they are willing to extend the credit.

Auto loans are also secured. You’ll find many lenders willing to offer you a bad credit auto loan, because they have the car as collateral: security in case you do not pay. If you fail to pay according to your bad credit auto loan terms, the lender will simply repossess the car.

If you’ve ever filed bankruptcy, you’ll see that you are swamped with offers for new credit cards and bad credit auto loans. This is because the lender is fairly secure in getting their car back. However, before accepting one of these offers, you should do some serious comparison of the terms and conditions that each lender offers. Be sure to find out:

- What is the interest rate on the loan, and what is the APR (annual percentage rate), which can be higher than the interest rate? The APR includes fees and costs and is the true interest rate you will be paying.

- What are the purchase terms of the loan? Are you required to use a certain auto dealership? Can you purchase out of state and save money, for example? How long do you have to use the funds (usually 30-60 days)?

- What is the total amount you will repay if you pay through the end of the loan term? This can alert you to other costs if it looks very high.

- Are there any prepayment penalties? Often banks charge a prepayment penalty to bad credit auto loan customers. This is a fee you will pay if you try to pay off your loan before the end of the loan term, or within a year or two of taking out the loan. The bank expects to make a certain amount of money on your loan, and the prepayment fees ensure that the bank is getting its money. These should be avoided no matter what; prepayment penalties just hurt customers that are already in financial trouble. (For example, if you want to sell the car, it shouldn’t cost you money to pay off your loan!)

- Can you afford the monthly payment? If you have bad credit, it’s likely that you are already having trouble making your monthly debt payments. Some banks will extend you much more credit than you need. Don’t get farther in over your head. You don’t have to use the full amount of the loan extended to you by the bank.

- Can you get credit for a trade-in? Sell or trade in an existing car before buying a new one. Save money by selling your existing car before buying a new one, and use the proceeds as a down payment. Don’ keep more cars than you need, and save on the costs of repair, maintenance, inspections and more.

- What are the late fees that you will be charged? These can be buried in fine print.

- What other hidden fees are included? Sometimes there can be a large up-front application fee, fees to run your credit, or other fees. Be sure to compare all other fees.

- Who is the lender offering you the loan? There are plenty of fly-by-night loan brokers who will send you offers in the mail, hide the fees, and insist they are “helping” you because you have bad credit. The fact is that reliable national lenders also have loan programs for bad credit auto loans that are much easier on your pocketbook. Also, don’t go for the loan offered by the dealership. They almost always contain less favorable terms, because the dealership is making some cash on the loan as well as the lender. Comparing loan terms and using the best lender can save you hundreds of dollars a month.

Today there is so much competition for auto loans among lenders, you can find good deals even if
you have bad credit or have a bankruptcy on your record. Taking out a car loan, if you find the right loan, is an excellent way to rebuild your credit.

Do it yourself Helpful Tips for Online Auto Repair

Learn how to easily repair your own vehicle with step-by-step instructions using online auto repair advice. Save money and make automotive repairs fast and fun.

Consider professional online auto repair advice when it comes to repairing your own vehicle. You may just avoid a complete disaster. Your vehicle is a big investment and it should be treated as such. When it comes to auto repair two things can happen. You can be successful and fix it right the first time. Or you can make matters worse by creating additional problems. The latter will increase repair costs and down time of the vehicle.

Let me give you a real life example of this. I had a young man e-mail me for help with a no start condition. My first advice to him was to get some online auto repair tips from a quality manual, to properly diagnose the problem. My favorite online auto service manual has the greatest no start diagnostic charts in the business, because they come straight from the factory auto service manuals. Easy to follow tree charts with pictures and helpful tips.

The young man told me he could not afford the $24.95 and he thought replacing the distributor would fix the problem. A new distributor was $650.00.He bought and replaced the distributor but this did not solve the problem. It was also not returnable like most electrical parts. Again I said cut your loses and get any kind of auto service manual and diagnose the problem, do not through parts at it.Well He replaced the coil, cap, rotor, wires and spark plugs. It Still would not start. Now he is a thousand dollars deep in un-needed parts. The guy who could not afford $25. Finally he towed the car to the auto repair shop and they fixed it for about $500.00 by replacing the fuel pump. As a side note I did try to help him by explaining, in a no start condition you either have no fuel or no spark (or rarely no air). The young man explained he was getting plenty of fuel. But he was not.

So $1,850 later he was motoring again. And to let you know step 1 on the diagnostic tree chart was an in-depth procedure with pictures for checking for fuel delivery. Also the online repair manuals had a technical service bulletin on the fuel pump for this specific vehicle. This is why the online auto repair manual can help you. What if you had the same auto repair information that the dealership level mechanic has? But in a format that provides step-by-step instructions and pictures that a person of any skill level can follow. The virtual online auto repair tips system was created to bring top-level information to the do it yourself auto repair public. Quickly find the auto repair information you need fast and simple with the online auto repair manuals handy search function. Just type in the component or area of the vehicle you need assistance with and the online programs gives you with just what you’re hunting for.
