Research on the Integrated Design of Dual Mass Flywheel CAD/CAE/CAM

Combining the research and development of dual mass flywheel, the paper explores the realizing methods of CAD/CAE/CAM integrated design system. The system is composed of modules including digital structure design and simulation, entire-car NVH analysis, analysis and optimization of formation process and welding process. Based on PDM technique, data sharing and integration could be realized through corresponding interface procedures by establishing a uniform product data model. The paper studies on the digital structure design and simulation, torsional vibration analysis, sheet material forming technology simulation and welding technology simulation. Finally the paper shows the comparison between one type of dual mass flywheel sample test curve and simulation curve.
