双重标准下的车辆安全性优化设计研究
Vehicle safety optimization design under double standards
摘要
Abstract
The peak deceleration extracted from new car crash test and the deceleration of pedestrian shanks were regarded as constraint variables when defining optimization problem under double standards.Let the specifications and the foam strength of buffer beam,front longitudinal beam and buffer coating as design variables,the quality of vehicle front structure was carried on optimization design by the validated vehicle truncation's finite element model.The optimal Latin hypercube experimental design and radial basis function method were used to create the approximate model of constraint function,the objective function was con-structed further and the optimal solution was obtained through genetic algorithm.Results showed that the design size obtained by the optimal solution made the quality of vehicle front structure significantly reduced,and met the double requirements of vehicle front head-on collision crashworthiness of rigid obstacles and pedestrians collision safety stipulated by the relevant regulations at the same time.关键词
