Research on Redress System of Vibration Table in Multi-Parameter Combined Environment Test System

Article Preview

Abstract:

The coupling between vibration and centrifugal field is quite strong in multi-parameter combined environment test system. The motion part of vibration table deviates from its original operation position by the action of centrifugal force, which ends in the stuck of armature and causes damage to vibration table. In order to solve such problem, an air-push-type armature redress system with displacement feedback was proposed, which provided a recovering force to counteract the centrifugal force and pushed the motion component to its designed operation position. Some improvements were also made to enhance its reliability. The result of simulation and test about the armature redress system demonstrates that the system has an excellent performance and meets the requirement of counteracting the centrifugal force, which guarantees that the vibration table could work in centrifugal field and multi-parameter combined environment.
