- To predict dynamic characteristics of hydraulically damped rubber mount (HDM), some key parameters in lumped-parameter model of HDM, such as volumetric elastic characteristics of fluid chambers and equivalent piston cross-section area of upper chamber, must be determined in some special ways because of difficulty in experimental measurement. In this paper, a kind of simulation approach of volumetric elasticity is developed by using finite element (FE) code of ABAQUS on the basis of hydrostatic fluid-rubber interaction modeling method. Contributions of different rubber parts to volumetric elastic characteristics are revealed. Predications of dynamic characteristics and frequency response analysis of a typical HDM with fixed-decoupler verify the effectiveness of the proposed parameter identification method.
