Abstract:

The rubber material's hyperelastic model constants are characterized based on test date.The structure model and the fluid model of light vehicle cab's hydraulic mount are established,and imported into Adina.The fluid-structure interaction model is established by Adina.The hydraulic mount's static characteristics are analyzed using quasi-static method.For dynamic characteristics analysis,the flow model of fluid is assumed to be turbulent K-Epsilon RNG.Dynamic stiffness and loss angle of the hydraulic mount are simulated based on this finite element model.The simulations of static and dynamic characteristics agree well with test results.The effects of primary structure parameters to the dynamic characteristics of the hydraulic mount are analyzed based on the finite element model.

Key words: vehicle engineering, light vehicle’s cab, hydraulic mount, fluid-structure interaction, finite element analysis
