Vibration Response: Calculating Vibration Response

February 02, 2015

Vibration is a unique concept in that it can be both a desirable and undesirable form of energy. It can be created by a simple motion and then move on its own until it returns to its natural, resting state. It can also be generated by a mechanical force that causes the vibrations on a regular basis. To protect some materials and components, there are a number of protective measures that can include vibration isolators or vibration dampers. There are some materials that can perform both types of actions for the object.

A vibration isolator helps to reduce the natural frequency of vibrations in a system. A vibration damper, on the other hand, takes much of the mechanical energy out of the system. Examples of each include springs, generally made of metal, which can be good isolators but provide no type of vibration damping, and foam based systems that can be good isolators but typically only live very short cycle lives because they become compressed and start failing. Once a foam system has become so compacted that it ceases to provide the right type of response, it can be said to have failed.

Vibration, at its negative point, can waste energy, cause a number of different types of damage and may cause unwanted sounds. It is important to know whether or not vibration is needed and if so, how it can be controlled within the object in question. That is why the formula for calculating vibration response becomes so important. If you do not use the right type of material, you will still have problems with vibration. Because vibration can shorter the useful life of an object, it is important to get this figure correct.

Sorbothane is one of the few materials that can be used interchangeably for a number of purposes. It can be used as a shock isolator or damper and can also be used to protect against other types of damages. But it is important to know what kind of Sorbothane you need to use and how much is appropriate. There is a formula that is used to calculate the vibration response, which is available in the design guide. To use it correctly, you must understand the concept of loaded and unloaded zones, which is the first step in the process. There are other calculations that you will need to make to get your final result. You must also figure the shape factor, the shear modulus and the natural frequency. There are a lot of numbers that you will be looking at when you calculate vibration response.

There are several kinds of limitations to different materials. Some may have limited strength, while some may be too stiff for certain applications. However, Sorbothane is a material that uses two different properties, taking the best of both types.

Using sorbothane is effective, but it must be used correctly and in the right surface size. That is why it is so vital to use the vibration response calculating formula.
