Abstract
Virtual Prototyping (VP) technology is a multidisciplinary and leading-edge focus which integrates CAD, CAE and visual technologies, etc. Usually, better simulation result can be obtained by using the VP technology. A modeling method for dynamics simulation of flexible-rigid mechanism was proposed. Based on dynamics equations of flexible-rigid system, the virtual prototyping of mechanism was constructed. In order to improve the accuracy of model and the reliability of simulation, the coupling of rigid-body movement and elastic deformation was considered. Errors caused by joint clearance, friction force and manufacturing would apparently affect the simulation result. Therefore, it is feasible that some characteristic parameters of system are adjusted according to experiment data. Then the adjustment of these systematic parameters could compensate the influence of the above factors. The modeling and simulation flow were detailedly discussed based on VP simulation and experiment results. A technological application of crank-slider mechanism demonstrated the validity of the presented method. The model for dynamics simulation was constructed by integrating 3D entity modeling, finite element method (FEM) and multi-bodies system (MBS) technology. Comparison between simulation solutions utilizing this method and experiment results shows a good agreement.
