Examples show that to solve the green charm problem and protect environment only by people＇s responsibility and duty is far from enough. The most important is to attract people loving the green product from the bottom of their heart and to realize the harmonious union of the nature and human beings.展开更多

Furthermore, advances concerning multi-material light weight design were presented by examples for aluminium solutions in advanced “Multi-material” Super-Light-Car （SLC） concepts, which reaches significant mass reductions.展开更多

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

In order to improve the performance of vehicle collision, eight parts were selected which have large impact for the result, its thickness as design variables to the right of the B-pillar acceleration peak of optimization goal;17 sample points were selected by Latin hypercube sampling method. Many structure parameters are optimized using sequential quadratic program (SQP) based on the surrogate model. The results show that the improved RSM has high accuracy;the right B-pillar acceleration reduced approximately 22.8%, reached the expected objective and was more conducive to the occupant safety.展开更多
