| Abstract: | Frame is one of the essential parts of motorcycle whose modal feature is one of the decisive factors for entire motorcycle vibration performance. A FE analysis of modal feature of a bent-frame motorcycle was made using MSC. Patran/Nastran software. The test result shows that the FE modal is OK. Then analyses of influences of the wall thickness of various parts upon the modal feature of the frame were made. Furthermore, the the influences of wall thickness upon the dynamic characteristics of the frame and the vibration of the motorcycle are verified by the experiments. |
