Abstract：A fluid-solid interaction capability is developed for the numerical simulations of Hydraulic Engine Mounts (HEM). The ALE finite element method is employed for viscous fluid flow, and linear elastic and hyper-elastic structure materials are used for modeling the steel and rubber, respectively. The full interactions between fluid and structure are considered by the strong coupling method. A Laplace equation-based mesh control method is used for moving the internal meshes of the fluid domain. The dynamic characteristics of the HEM are clarified by 3D simulations, and the comparisons of the numerical results with experimental results are demonstrated to show the reliability of the proposed methods.
