Abstract: Taking the rubber spring of a hydraulic engine mount for car powertrain as an example, the study method for finite element analysis (FEA) of rubber isolator was studied. The fundamental theory for the FEA of rubber component and process of the FEA model with nonlinear finite element softwareABAQUS were introduced. The different influence degree under different finite element models and structure parameters was calculated and analyzed. Then the influence degree under different stiffness rubber springs of hydraulic engine mount was analyzed. The effect and influence degree of rubber spring to hydraulic engine mount was reviewed, and a design direction of hydraulic engine mount was given.
Key words: hydraulic engine mount; rubber spring; finite element analysis (FEA); test
