Time histories of the main collisional parameters are presented,improvements of the frame are partially made according to simulation results. Collisional simulationof the tubular frame alone indicates that, such new type of bodywork for sedan car is of goodpotentialities to meet the collision safety regulations.展开更多

Ltd., and also a manufacturer of the Charade sedan cars of economy model. It is one of China’s four major sedan car production bases. In 1995, it formed a production capacity of 150 thousand sedan cars. The Charade sedan cars still occupy 60 percent market share of the national taxi market. The Tianjin Mini-Automobile Factory now has a total staff of 3,914. It covers an ama of 429,000 square metres,展开更多

In this paper, a CAE simulation analysis is made for a domestic sedan car hood to check whether it meet the pedestrian safety protection laws and regulations. Results show that the original car cannot meet the demands of the rules. In order to meet the standards of the pedustrian protection rules, the car hood should undergo structural improvements. Tested again by CAE simulation analysis, the car after a series of improved design can reached the 3-star class EuroNCAP( Euro New Car Assessment Program)standard of the car pedestrian safety protection laws and regulations.展开更多
