Shock and Vibration Control
Universal Power Conversion, Inc. (UPC) has many types of Shock and Vibration Controls to help protect your equipment from destroying itself. How do you determine if you need Vibration or Shock protection?
Tech Products explains Vibration as a magnitude (force, displacement, or acceleration) which oscillates about a reference point. Vibration is commonly expressed in terms of frequency, cycles per second or Hertz (Hz). Shock is normally classi?ed as a transient phenomenon in contrast to vibration that is normally a steady-state phenomenon. Shock isolation is considerably di?erent from vibration isolation.
Vibration problems generally fall into two classes.
Vibration problems generally fall into two classes.
- Force excitation: The isolator is used to protect the supporting structure from forces generated by the supported mass. An example is the use of motor mounts in an automobile.
- Motion excitation: The isolator is used to protect the supported mass from disturbances of the supporting structure. An example is the use of mounts under a coordinate measuring machine.
- Shock isolator stores the input energy by de?ecting and then releasing that energy over a longer period of time. The energy is released at the natural frequency of the shock isolation system.
- Shock is normally de?ned by a pulse or a free-fall impact. Some typical pulse shapes are half-sine, triangular, rectangular and versed-sine.
We carry American Acoustical Products, Tech Products, Sunnex and Ace/Enertrols to help you with your vibration and shock dampening needs.
