Title: RESEARCH AND DEVELOPMENT OF VIRTUAL PROTOTYPE OF RUNNING GEARS FOR RAILWAY VEHICLE
Abstract: Virtual prototype is an important idea to resolve design problems of railway vehicle. A different development method,which is based on national product and autonomous development,and would like to reflect the specialty of railway vehicle development in China,is presented. According to the developing process of railway vehicle,the research contents and developing method are pointed out. The integration between CAD and performance analysis software on dynamics and strength is mainly considered. In CAD environment,the properties for dynamics computing are extracted directly from the model and exported with model. This method can avoid data losing caused by model rebuilding in CAE software,and increase the direct dependence of product CAD. Then the vehicle model with properties will be used for real-time dynamics and kinematics analysis and simulation. Therefore,the strength of the parts can be analyzed. The results of dynamics and strength analysis will be fed back to optimize the design model. All operations are dispatched by a control platform,and all data are managed according to the principle of PDM. Testing results show this method is correct.
