摘要
为了提高汽车有限元乘员约束系统的建模效率、仿真精度及模型可替换性,提出了一种基于模块化的约束系统建模方法。基于安全气囊、方向盘、转向管柱、座椅、仪表板等零部件冲击试验,建立了某车的有限元约束系统子模块的INCLUDE文件。通过直接调用这些子模块INCLUDE文件,建立简化的约束系统模型。对比计算机仿真输出与正面100%重叠刚性壁障碰撞试验获得的假人伤害数据,结果表明:通过验证的模块化子模型组建简化的约束系统模型可以获得高精度的仿真结果。从而验证了该方法的可行性。
In order to improve the efficiency, accuracy and replaceability of finite element modeling of occupant restraint system, the accuracy of the simulation model and the replace ability, this paper proposed a high precision modeling method based on modularization. The restraint system of sub- module were built with finite element in INCLUDE files, and it was validated with component tests of airbag, steering wheel, steering column, seat, instrument panel and other parts. The restraint system model was established by directly called these sub-module INCLUDE files. Through comparing the simulation output with the test data of a certain 100% overlap frontal crash dummy injury data, it showed that the simulation results had a high accuracy with the verification of sub-module, and this modeling method was feasible.
