Abstract: Combined with finite element
method(FEM),the multi-body system simulation(MSS) method was applied to
investigate the vibration transmitting characteristics of engine cylinder block
in this paper.The multi-body dynamics model of engine block system is
established.The transfer functions based on the engine block vibration and the
main loads are obtained through simulation.
Keywords: Diesel Engine;Crankshaft
System;Multi-body Dynamics
