Research of modeling flexible-rigid system based on mechanism

A precise rigid-flexible virtual prototype model for crank-slider mechanism was established by the virtual real mixed modeling technology and using commercial software, such as the CAD software, the Finite Element software and the Dynamics Simulation software. The locomotion parameters of physical and virtual crank-slider mechanism were measured or calculated. The result shows that the locomotion parameter from the virtual prototype system is of good agreement with the test system. This work has offered a feasible approach for establishing and researching the rigid-flexible virtual prototype model.
