Dynamics Simulation of the Crank and Connecting Rod Mechanism of Diesel Engine

Abstract:

Based on the virtual prototyping technology and flexible multibody system dynamic theory, the author founded the rigid-flexible coupling multibody dynamic analysis model of the crank and connecting rod mechanism of diesel engine, combining the means of 3D solid modeling, finite element analysis and multi-body dynamic simulation. Through the simulation, the dynamic loads in the working cycle of the mechanism are obtained, which provides reference for dynamic stress and fatigue analysis of the mechanism.
