The crankshaft in the transmission chain of the engine is simulated and analyzed.The influence of stiffness,moment of inertia and bending moment of the crankshaft dual mass flywheel,clutch,transmis-sion spindle,transmission housing and oil pan on the simulation results are considered.Thus the model of the parts is reduced,the bush line is optimized,and the heat load,total pressure and rough contact pres-sure are reduced.The simulation results show that the minimum fatigue factor of crankshaft meets the de-sign requirements.
