| 摘 要： | Based on the analysis of experimental model, the vibrating experiment was made for the frame and engine of motorcycle in order to find the resonance frequency of the frame. Then the effect of engine exciting on the body vibration was analyzed, so that the mode frequency avoids the range of engine rotation speed. The experiment results show that the vibration of the saddle in vertical direction and the handlebar are caused by the resonance, while the vibrations of the other two directions of saddle and the pedal are the result of the transmission of engine energy. In order to decrease the transmission of the engine energy to pedals, we can change the stiff welding between the pedals and the frame of the motorcycle into the elastic link. Furthermore, to avoid the resonance of the frame in vertical direction, besides increase the stiffness of the frame, we can reduce the stiffness of the frame under the condition of having sufficient intensity, so that the nature frequency of the frame is reduced below the operating speed of the motorcycle engine.

| Abstract: | Based on the analysis of experimental model, the vibrating experiment was made for the frame and engine of motorcycle in order to find the resonance frequency of the frame. Then the effect of engine exciting on the body vibration was analyzed, so that the mode frequency avoids the range of engine rotation speed. The experiment results show that the vibration of the saddle in vertical direction and the handlebar are caused by the resonance, while the vibrations of the other two directions of saddle and the pedal are the result of the transmission of engine energy. In order to decrease the transmission of the engine energy to pedals, we can change the stiff welding between the pedals and the frame of the motorcycle into the elastic link. Furthermore, to avoid the resonance of the frame in vertical direction, besides increase the stiffness of the frame, we can reduce the stiffness of the frame under the condition of having sufficient intensity, so that the nature frequency of the frame is reduced below the operating speed of the motorcycle engine. |
