Multi-Body Dynamics Analysis of V-Type Diesel Engine Crankshaft

Based on the V-type diesel engine crankshaft system, the paper combined the finite element method (fem) and multi-body dynamics method together, made a virtual simulation analysis. First, by 3d software and finite element software to establish the multi-body dynamic models of the crankshaft, bearing and piston, then simulated the actual engine working condition, and got the data such as crankshaft acceleration, velocity and displacement by the multi-body dynamics simulation analysis. By calculation, the paper found that by using the combination of finite element and multi-body simulation method, can we effectively simulate the diesel engine crankshaft dynamics characteristics.
