Abstract
In the process of launching, some launch bearing platforms will bear large impact force, thus causing severe vibration of the platform. There exists coupling relationship between this kind of vibration and the hydraulic system. In this paper, we established the vibration model according to the coupling vibration system in bearing platform and hydraulic system, and realized decoupling. Then we derived the vibration controlling equation and transfer function of coupling vibration between bearing platform and hydraulic system. Further more, we simulate the actual situation in software Simulink, and it gave vibration response curves under different parameters. In this way, it provides basis for reducing platform vibration.
