The filter capacitor installation is one of main noise sources in converter station.In this paper, the parallel capaci-tor providing by the company is taken as the research object to present a simulation method of vibration and noise of capacitor based on ANSYS and LMS.Virtual lab.First of all, mechanism of vibration and noise of capacitor are analyzed to get the boundary conditions of the finite element model of vibration and noise.Second, the simulation of vibration and noise of capaci-tor are made by ANSYS and LMS Virtual lab.Finally, a noise experiment test of the capacitor is made, and the simulation re-sult is compared with measuring values.Thus the accuracy of the simulation method of vibration and noise of capacitor is veri-fied.
