Research on Design of Elastic Isolator for Motorcycle Engines

Using an isolator to isolate the engine high frequency vibration was a very important method. The elastic vibration isolation system of engine was studied. And an elastic vibration principle and frequency design criterion were presented in this paper. The dynamics model of elastic system of engine was established and the dynamic characteristic parameters of the system were confirmed. After synthesizing analyzing the elastic isolator design requirements for the frame dynamic behavior and the test results, elastic isolators were designed. The research results showed that the elastic isolator could effectively separate the high frequency of engine from the frame.
