Using a Vibration  Shaker with Vibration Controller

Video Demonstration with Dual Purpose Vibration Shaker Model 2075E

Vibration testing is generally used to test a product's ability to resist dynamic loads while maintaining critical functionality or structural integrity under specified loads. As part of a company's quality assurance program this testing be used to identify mechanical weaknesses or other performance flaws from accumulated stress effects from the vibration input

Often, an industry standard such as MIL-STD-810, IEC 60068-2, ISO 16750-3, and others, specify the required frequency and amplitude content of vibration for testing. Using a shaker paired with a vibration controller allows the shaker to provide a user-defined frequency and amplitude specification to meet the requirements of such a standard. The following video demonstrates the operation of the Dual Purpose Vibration Shaker Model 2075E with a vibration controller. In this setup, a piezoelectric accelerometer mounted to the Vibration Shaker sends feedback to the vibration controller so that the shaker stays at the desired levels for a given test.

Common Types of Vibration Tests

  • Random Testing: Subjects the device under test to random noise
  • Swept Sine Testing: Simulates real-world vibration of rotating machinery
  • Shock Testing: Measures reliability and durability with tests using pulse shapes such as half-sine, haversine, terminal-peak saw tooth, initial-peak saw tooth, triangle, rectangle, and trapezoid.
  • Time Waveform Replication Testing: Exactly replicates a vibration in its time waveform format to accurately reproduce data collected in the field
