摘要

为了解决驾驶员系统多目标优化的约束和高度非线性问题,根据汽车的相关尺寸,我们建立了混合动力III第50代虚拟驾驶员约束系统的仿真模型。实验数据的驾驶员力学指标与正面碰撞模拟数据的比较表明,模拟模型的精度满足要求。采用最优拉丁试验设计,并基于克里格模型对设计参数进行全局灵敏度分析。选择了四个最敏感的参数,并通过多岛遗传算法对这些参数进行求解。然后利用非线性规划二次线(NLPQL)算法进行精确优化。确定了乘员约束系统的最佳参数:限力器2的极限力值为985.603N,安全带伸出量为12.684%,安全气囊点爆炸时间为27.585ms,安全气囊通风口直径为27.338mm,加权损伤标准(WIC)降低了12.97%,头部损伤降低了22.60%,结果表明,安全带、安全气囊等被动安全装置的系统集成可以有效地保护驾驶员。

Multi-Parameter and Multi-Objective Optimization of Occupant Restraint System in Frontal Collision
To solve the constraints of multi-objective optimization of the driver system and high nonlinear problems, according to the relevant dimensions of a car, we build a simulation model with Hybrid III 50th dummy driver constraint system. The comparison of the driver mechanics index of the experimental data with the simulation data in the frontal crash shows that the accuracy of simulation model meets the requirements. The optimal Latin test design is adopted, and the global sensitivity analysis of the design parameters is carried out based on the Kriging model. The four most sensitive parameters are selected, and the parameters are solved by a multi-island genetic algorithm. And then the nonlinear programming quadratic line (NLPQL) algorithm is used to search for accurate optimization. The optimal parameters of the occupant restraint system are determined: the limiting force value of force limiter 2 985.603 N, belt extension 12.684%, airbag point explosion time 27.585 ms, and airbag vent diameter 27.338 mm, with the weighted injury criterion (WIC) decreased by 12.97%, the head injury decreased by 22.60%, and the chest compression decreased by 7.29%. The results show that the system integration of passive safety devices such as seat belts and airbags can effectively protect the driver.
