Vibration Forecast and Vibration Attenuation Research of the Finished Motorcycle based on Virtual Analysis

摘要

As the high-speed vehicle, motorcycle vibration has an important influence on driving security, comfort, and handling stability. Therefore, this article builds the finite element analysis model of vibration forecast and damping of the finished motorcycle based on the structural characteristics. The major contents include main part modeling, boundary condition, and the finite element model of the finished motorcycle. In the paper, we build the finite dynamic response equation through analyzing the dynamic response, and research the resonance from different directions that caused by the engine harmonic response. Moreover, this article provides the vibration attenuation plan of the motorcycle structural modification and proves the feasibility through the analog computation and experimental measurement.
