In order to analyze the torsional vibration of the crankshaft system, a three-dimensional model of the crankshaft system is established, consisted of the piston, connected rod, crank shaft, flywheel and silicone oil damper. Use by multi-body dynamics simulation software ADAMS, created the multi-body dynamics model of the multiple degrees of freedom consisting of rigid hybrid engine system, to do the torsional vibration response simulation, analysis of the torsional vibration on the crankshaft. Through the torsional vibration test of the diesel engine crankshaft system, the accuracy of the simulation calculation results have been verified. This simulation result has higher accuracy, and this calculation method has certain engineering application value.
