Simulation Research on Strong Fluid-Solid Interaction of Hydraulic Engine Mount

摘要

This paper sets the hydraulic engine mount (HEM) of a car as its research object and established the strong fluid-solid interaction finite element model for its property analysis by adopting the INTESIM strong fluid-solid finite element method. A stimulation analysis of the model's static and translation dynamic stiffness characteristics was conducted, compared with the experimental result and the effectiveness of the simulation research findings was verified. The research demonstrates that the translation dynamic characteristics of the HEM can be effectively simulated by the INTESIM strong fluid-solid finite element method; on the basis of which, a preliminary discussion on its torsion dynamic stiffness characteristics was carried out also.
