However, under the excitation of low frequency and large amplitude, the decoupling film and the upper and lower limiting plates are impacted and generate noise, so that the service life of the semi-active hydraulic suspension is shortened, and meanwhile, the high frequency noise reduction capability of the semi-active hydraulic suspension cannot meet the increasingly-improved automobile comfort requirement.
