Technical Analysis and Improvement of the Pedestrian Safety Protection of a Car Hood

摘要

The pedestrian protection technology must be used in automotive design if China-made automotives want to compete and grow strong in the world in the future. 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.
