Abstract

Using flexible multibody system dynamic method,this article founds the rigid-flexible coupling multibody dynamic analysis model of the crank and connecting rod mechanism based on ADAMS software platform,and processes the kinematic and dynamic simulations taking the crank and connecting rod mechanism of D6114B engine as its object of study.Through the simulation this article obtains the dynamic characteristic data such as the loads of main bearings and connecting rod bearings,the inertia forces of pistons and connecting rods,and the output torque and power of the engine.It gives the foundation for the design of the crank and connecting rod mechanism of automotive engine.
