Shock and Vibration Control
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.
