＜正＞In order to reduce energy consumption and protect the human survival environment,the lightweight has became the development trend of the world automobile industry.On the premise of ensuring the strength,safety and driving performance of the car,the major car enterprises try to reduce the curb weight of the car,fuel consumption and emissions.Not only a lot of new technologies and new products have been generated,but also joint vehicle development process and computer aided engineering（CAE） analysis technology have been developed.Since the entry into the "Automobile Lightweight Technology Innovation Strategic Alliance" in Dec.2007,Geely Group has been focusing on lightw eight construction of vehicle and key assemblies in every stage of the vehicle product development.Among vehicles appeared on the market and in research,it has presented continuously better performance.The paper describes application examples and successful experience of CAE simulation analysis and performance optimization during the lightweight design and development of a self-developed model of Geely,and looks forward to the prospects for the development of lightweight of Geely vehicle.
