摘要：

In view of the difficulty in accurately setting up multi-field coupling model for the optimization of semi-active mount, ADINA software is adopted to establish a liquid-solid-gas three-phase coupling simulation model for semi-active engine mount, and a lumped parameter model for semi-active mount is also acquired by accurate identification and extraction of key parameters, with its dynamic characteristics studied. The results show that the ADINA-based liquid-solid-gas three-phase coupling simulation model can rapidly and accurately extract the key parameters in lumped parameter model, realizing the accurate prediction on the dynamic characteristics of semi-active mount. The correctness of multi-field coupling modeling and dynamic characteristics analysis method are verified by tests, providing a feasible scheme for the forward development and structure optimization of the semi-active mount of automotive engine. © 2017, Society of Automotive Engineers of China.
