基于HyperWorks的三点式安全带固定点座椅强度分析

Based on HyperWorks, the seat strength analysis of three-point seat belts

汽车被动安全的重要指标之一就是安全带固定点强度,而三点式安全带对于汽车座椅提出了更高的挑战。文章利用HyperWorks优秀的前处理技术,建立汽车座椅、三点式安全带总成及人体模块的有限元仿真模型,利用LS-DYNA求解器进行安全带固定点强度分析。从而判断汽车座椅的安全带固定点的变形情况和座椅部件的应力应变,判断座椅是否有风险。

One of the important indicators of car passive safety is the strength of the seat belt,and the three-point seat beltposes a higher challenge for car seats.Before using HyperWorks excellent processing technology,the establishment of carseats,three-point seatbelt assembly and body module of finite element simulation model,using ls-dyna solver for seat beltprotection strength analysis.To determine the condition of the seat belt and the stress strain of the seat parts to determinewhether the seat is at risk.
