| Abstract: | This paper uses experimental modal analysis method to analyze a drive line fracture accident due to the insufficient critical speed of the drive shaft when the vehicle runs at high speed. The influence of backlash in drive line on the modal test is discussed. Finally, the correct test method is given and verified by dynamometer test. |
