The Development of the Closed-Loop Control System for the Mechanical Suspensions Test Rig

Abstract:

Frequency and amplitude of the existing mechanical suspension performance test rig can not change. And it has signal function. Frequency changing devices and amplitude adjustment mechanism were designed on it by study. Frequency and amplitude of the improved test rig can change within a certain range. It has two control algorithms: fixed-frequency vibration and sweep vibration. And the used closed-loop control in the system ensures the reliability of the system. The results show feasibility and correctness of this control system by a large number of experiments. It improves the function of the test rig and decreases the cost of study.
