Highlights:


  • Minimizes Over-testing
  • Reduces Risk of Damage to Critical Structures
  • Measures Summed Forces
  • Measures Moments
  • Simplifies and Expedites the Test Process
  • Convenient and Easy to Implement

The PCB® Force Limited Vibration Testing System meets the requirements for limiting the reaction force between the shaker and unit under test in vibration testing. The use of piezoelectric, 3-component force sensors facilitates easy measurement of the input force. This force relates directly to the quasi-static acceleration of the structure’s center-of-gravity. Used in the vibration shaker’s feedback control loop, the force signal is compared to established force limits in the controller. At frequencies where the measured force exceeds the limit (at high Q resonances), the controller’s output signal (i.e., the input signal to the shaker) is “notched.” By reducing the input to the shaker at these frequencies, the reaction force between the test fixture and structure is maintained within specified limits.
