MADYMO-based Simulation Study on Parameter Optimization of Restraint System for Child Occupant

对汽车正面碰撞儿童乘员约束系统的参数优化进行仿真研究,运用MADYMO软件建立儿童约束系统仿真模型,并进行参数优化仿真,利用参数灵敏度来分析伤害指标的优化程度,将仿真结果进行对比验证,最终确定最优模型参数组合。该研究为儿童乘员约束系统的优化设计提供参考。

A simulation study is completed on parameter optimization of the restrained system for child occupants in case of front car crash;MADYMO software is adopted to establish a simulation model for child restrained system for simulation of parameter optimization.Parameter sensitivity is used for analyses of the optimization level of the injury indices to compare and verify the simulation results and ultimately determine the optimal combination of model parameters.This investigation has furnished references in optimum design of the constrained system for child occupants.
