| Abstract(E) | In this study, we efficiently predict the vibration response of a design shape at a low computational cost in the early development stage, select design proposals with good characteristics from many proposals devised by the designer at the early stage, and forward them to the next stage to achieve the front-loading of development while increasing product value. The application of participation factor (PF) focusing on the response at a specific part for vibration evaluation of a motorcycle frame is described. To reduce the motorcycle frame vibration, an eigenvalue analysis was performed, and appropriate design change proposals were efficiently selected using partial participation factor (PPF), an index showing the relevance of vibration of specific parts or positions. Using the PPF, we extracted which vibration modes considerably contribute to the vibration response of the part of interest. The mode shapes of the extracted vibration modes were all those in which the rear frame part was torsionally deformed. Therefore, the torsional vibration was considered a cause of the vibration evaluation to be insufficient, and some frame design change proposals for suppressing the torsion were proposed. In addition, the effect of the design change proposals on the selected shape was verified. |
