TLDR
The methods for simulating the system in the lumped model and the numerical predictions model for modeling PHEM are effective, with which the dynamic characteristic analysis and design optimization of an PHEM can be performed before its prototype development, and this can ensure its low cost and high quality for development.Abstract:
Dynamic modeling of Passive Hydraulic Engine Mounts (PHEM) is developed with inertia track, decoupler and throttle. Mathematically, the state equations governing vibration isolation behaviors of the PHEMs are presented and solved by means of the lumped parameter method. Numerical results are produced for low and high frequency responses of the engine mounts. It is shown the engine mounts are possessed of better dynamic performance characteristics such as frequency-dependent and amplitude-dependent. The experiments are made for the purpose of parameters designs and validation of the PHEM. It has been shown by comparison of the numerical results with the experimental observations that the present PHEM achieves fairly good performance for the vehicle industry. The work conducted in the paper demonstrates that the methods for simulating the system in the lumped model and the numerical predictions model for modeling PHEM are effective, with which the dynamic characteristic analysis and design optimization of an PHEM can be performed before its prototype development, and this can ensure its low cost and high quality for development.read more
