Abstract

Vibration of the automotive engine has the characteristics of wide frequency band, multi-vibration sources and multi-main frequencies. Limited capability of passive mounting systems can be provided for engine vibration isolation. A MR semiactive mounting system for automotive engines is investigated in this paper. The dynamic model of the vertical vibration isolation system for the engine and an efficient damping control model of the MR mount are established. The frequency characteristics of the engine vibration are analyzed. The fuzzy control algorithm for the MR mounting system is designed, and the isolation performance of the MR mounting system is analyzed based on the developed experimental setup in Hefei University of Technology.
