| Abstract: | This paper presents an analytical method that can calculate the natural properties of torsional and longitudinal vibration of an engine crankshaft in continuous mass system.Taking a six-cylinder diesel engine as an example,a continuous mass model of the crankshaft is set up.According to the analytical method of the continuous mass system,the natural frequencies and models of the longitudinal and torsional vibrations are calculated.Compared with the measured results and the calculation results on the discrete mass system,the calculation results on the continuous mass model are verified to be of higher precision. |
