Analysis of Chest Rib Deflection Performance Improvement Based on a Specific Vehicle Euro NCAP Side Pole
This article is based on the overall safety development of a new energy vehicle model Euro new car assessment program(NCAP),to conduct the performance study on the chest deflection problem on the side pole test condition.Through the theoretical research on the chest deflection problem and obtain the relative influence factors.And by using the research method of finite element simulation analysis,sled test and vehicle barrier test verification.The optimization of BIW structure,airbag layout,seat foam design is proposed,which finally improved the vehicle crash performance.This article shows that the safety space of occupant,the safety restraint on the dummy,the stability of the seat state,etc.,all have an important impact on the chest deflection performance,and the proposed solution is verified by the vehicle test and to be believed that is feasible.
