Some typical applications of aluminum alloy automotive sheet to automotive industry are listed. Based on the author＇s knowledge and recognition and research progress presently, the important re- search contents about aluminum alloy automotive sheet are emphasized. Reducing cost and price of sheet and going deeply into application research are the main work for expending the application of aluminum alloy automotive sheet in the automobile.展开更多

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
It is more positive and instructive attempt for the Virtual Reality technology to be used in the education of automobile repairments. And it give us a new method and direction to professional education reform.

According to the common automotive steel product from the major steel plant in China and usage situation in local automotive OEMs （original equipment manufacturers）, a standard LS-DYNA material database contains 129 kinds of commonly used metal material and database is developed by CATARC. Considering the frequent use of material data and applied to different parts in FE model, engineers can save time with this standard tool and meet the future request of the automation modeling process.展开更多
