VIBRATION TESTING


Powertech has two electro-dynamic shakers offering vibration testing and shock testing. This equipment has force ratings of 13,500 lbs with shock loads of up to 250 Gs. In addition to these services, we are able to combine vibration and environmental testing  by incorporating both a small scale shaker and a Thermotron environmental chamber.

 

Our capabilities include:

Vibration Test System

Vibration Test System

  • Vibration: sine wave or random vibration profiles (up to 13,500 lbf)
