How To Choose Vibration Control Systems

Waves of vibration

Vibration control can be defined as the application of a certain amount of force that is both equal and in opposite fashion to the forces being caused by external vibration. The primary purpose of this is structural control, in order to reduce or cancel out the problems caused by vibration to sensitive instruments or equipment. This process has several different applications.

The most common ones are vibration reduction systems for precision industrial processes, which allows the user to control the motor vibration of industrial instruments by using the correct vibration equipment, typically a platform on which the equipment is placed. It helps in reducing vibration in helicopters, for a smoother and more comfortable ride. Exercise vibration equipment, which makes use of the three types of vibration (circular, flat, or tilt), helps with the target training of certain muscle groups in the human body.

When selecting anti-vibration equipment, it is important to do vibration testing in order to correctly determine which type of VCS, or vibration control system, is apt for the application that you desire. The following are tips on how to select the proper vibration control system for your specific use:

  • Vibration Exercises. When doing vibration exercises, the three types of vibration are put into use for the benefit of specific target areas in the body: circular, flat, and tilt vibration. It has been noted that the circular vibration, which involves a ball-shaped motor that vibrates the plates in a circular manner, creates the side effect of a horizontal motion, which may cause injury to the user. On the other hand, research has proven that flat vibration is quite ideal for strengthening the upper body, and for use in exercises that require the user to stand on one leg. Finally, the tilt vibration seems especially beneficial for exercises that serve to strengthen and train the lower body, largely due to the fact that it induces a seesaw motion, which tends to simulate our natural human movements.
  • Precision Industrial Processes. For precision industrial processes that cannot be undergone if affected by machine vibration, there are two main types of vibration control systems: active vibration control and passive vibration control. In the past, passive vibration control was the only option, and it involved the use of basic equipment such as shock absorbers, dampers, and a base isolation method, to control machine vibration. Active vibration, on the other hand, is a more advanced system of vibration control, which typically involves the use of several different components. These components are a suspended platform, several accelerometers (to measure the acceleration of movement), an electronic amplifier system (to magnify and reverse the signals coming from the accelerometers), and, for very large equipment, the proper hydraulic or pneumatic components needed to support the activity. The type of system you use, whether passive or active, depends primarily on the needs and requirements of your machine, and of your industrial processes.

Whatever the purpose of your activity, selecting the proper vibration control system requires a certain amount of research and trial and error. As long as you have a clear idea of what you would like to accomplish, you should not have a problem selecting the proper VCS to suit your needs.
