The results from earthquake testing are used to optimize the design and material properties of the unit under test. A vibration control test is one of the most reliable ways to carry out this type of dynamic testing. An earthquake profile is programmed into the controller and the shaker table then simulates this movement.

Shaker Testing Introduction and FAQ. Simulating the everyday life of any product is an integral part of its test and validation process. Shaker testing allows you to predict the failure modes of an equipment or component and monitor their dynamic behaviour to improve their reliability.

A shaker can be used to simulate launch vibrations and check responses of structures forced at different frequencies. When vibrating at certain frequencies during tests, structural modes of the shaker table itself can cause the test to abort by accelerating too much or by pushing too much electrical gain through the system.
