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 ear, 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 ＂Au- tomobile Lightweight Technology Innovation Strategic Alliance＂ in Dec. 2007, Geely Group has been focusing on light- weight construction of vehicle and key assemblies in every stage of the vehicle product development. Among vehicles ap- peared 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 de- sign and development of a self-developed model of Geely, and looks forward to the prospects for the development of lightweight of Geely vehicle.展开更多

The results show the organizational slack that explored and employed reached to a critical point and can promote enterprises to choose the independent innovation strategy based on R & D (Research and Development); And it is important to identify,explore and employ organizational slack correctly for strengthening the organizational independent innovation capability and raising its performance when the technological innovation strategy based on technological introduction is more and more difficult.展开更多

In the global market strategy of ＂whoever sets standards wins the market＂, it is the technological leaders that as relevant standards developers take the initiative on the world market. Therefore, from mainly addressing the universality and interoperatability of product parts in the past, technical standards have been respected as the new technical concept and gradually become the commanding height of the industry competition.展开更多
