Control and Limiting Strategies for Random Vibration Tests on Spacecraft Subsystems

Controlled vibration tests on complex spacecraft subsystem some times present several challenges to test engineers. In such cases, adopting proper control strategy becomes crucial so that the test article or subsystem undergoes a vibration test as per the test profile while safeguarding the shaker system. This paper presents different control/limiting strategies that are adopted while conducting a vibration test on spacecraft subsystems considering the safety of the subsystems and shaker systems.
