Abstract

Abstract--The dynamic characteristic test of the decoupling disc hydraulic mount designed by ourselves was performed firstly to establish surely the accurate simulation model of the hydraulic engine mount. In order to study the particular dynamic characteristic of the homemade decoupling disc hydraulic suspension, the test was measured under different working conditions. The test revealed the working mechanism of the hydraulic mount, and provided the design basis of the hydraulic mount structure and the theory of engine mount optimization. The experiment showed that under the same frequency, the dynamic stiffness increased with the load increasing, the lag angle, however, decreased with the increase of pre-load. Meanwhile the results also showed that as a whole, the dynamic stiffness and the hysteresis angle decreased with the increasing amplitude, but on the whole frequency band, its nonlinear characteristics of the dynamic stiffness changed evidently with the excitation amplitude.
