Force Limited Vibration Systems

PCB’s Force Limited Vibration Testing Systems minimize over-testing and reduce the risk of damage to critical structures by using multi-axis ∑ forces and measuring moments as inputs in a closed loop control system to an existing large shaker or slip table.

Conventional control using acceleration has been shown to cause significant over-testing that may result in damage to the unit under test (UUT). Due to the high cost, long development times, and uniqueness of sophisticated aerospace and other high-tech equipment, it has become imperative to implement techniques that ensure the safety of such items during vibration qualification testing. In force limited vibration testing, the total input force to the UUT is measured and controlled, thereby limiting the “quasi-static” acceleration of the center-of-gravity and ensuring the integrity of the equipment.


PCB Force Limited Vibration System Benefits:

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