摘要
安全带是汽车安全零部件中重要的零部件之一,国家出台了相关的法律法规对汽车的安全作出明确规定,在试验载荷情况下,安全带固定点的强度必须保证安全带不得从安装固定点处脱落。文章借助于有限元分析软件对安全带固定点强度展开分析和优化,对约束的定义、加载函数的选取、模型建立等进行简要阐述,最后,将仿真结果与实际试验结果进行对比分析,说明仿真计算具有较好的精度,能够满足工程的实际运用。
The seatbelt is one of the important parts of automobile safety components.Countries have also introduced the relevant laws and regulations to the safety of the car in the specified test loads,seatbelt fixed point strength must ensure seatbelt shall not install from a fixed point off.In this paper,with the help of finite element analysis software to analyze and optimize the fixed point of strength safety,constraint definition,function selection,load models are briefly described.Finally,the simulation results and actual test results were analyzed and the simulation shows that with better accuracy,which can meet the practical application of engineering.
