In this paper, the method of calculating crankshaft torsional vibration using finite element beam element is discussed. The calculation model and boundary conditions of crankshaft torsional vibration are studied, and the calculation of natural frequency and forced vibration are carried out. The calculation results are consistent with the experimental data.
