As the core of power generation and transmission of vehicle; powertrain system provides and transmits power to transmission mechanism while generating vibrations which is the main source of vehicle vibration. As a part of the whole vehicle, powertrain while driving will be influenced by the outside interference. Independently studying powertrain vibration isolation performance can not meet the actual requirement in the process of car driving. Therefore, this paper studied vibration isolation characteristics and optimization design of powertrain-vehicle system with energy decoupling method. After the vibration transfer rate and the frequency response analysis, the energy decoupling method is effective for the improvement of mounting system＇ s vibration isolation performance.
