Abstract: With the progress of society and the popularization of vehicles, the vibration and comfort of vehicles gets more and more attention from users. Based on the forward design of engine suspension based on the principle of six degrees of freedom decoupling, the natural frequency of powertrain was analyzed and designed, and the basic decoupling of six degrees of freedom in all directions was realized. It not only improves the success rate of one-time development and the control of development cost of the whole vehicle in the development cycle, but also provides theoretical optimization and rectification suggestions for the subsequent actual evaluation and adjustment of the vehicle, and reduces the trial and error rounds in the development process.
