| Abstract: | The frame is an important part of vehicle chassis. Its quality has an effect on the quality of vehicle and further affects the property of vehicle’s emissions, power, comfort and fuel economy. Frame lightweight can improve the performance of the vehicle in all directions. Frame lightweight has become the focus of attention of researchers. The new material has advantages of high strength, light weight and corrosion resistance,et al. The new process has advantages of high precision, fast processing. Structure optimization has advantages of low cost and quick effect. So,how to use these three ways to achieve frame lightweight become current research hotspot. The research status of lightweight of the fringe-beam frame at home and abroad was introduced, the difficult problems and solutions of current research were discussed and the future directions were predicted. |
