摘要
安全带固定点强度是汽车被动安全的一个重要指标,国家强制性法规明确要求,在承受规定点试验载荷情况下,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.笔者结合长安SC1020微型货车,探讨了利用有限元方法对安全带固定点强度进行模拟计算的问题,给出了可行的计算模型、边界条件和优化设计方法.
It is a important criterion of the fastened point intensity on automobile safe belt.The compulsive regulation of the country clearly requires that the fastened point intensity on the safe belt must ensure that the safe belt can't be broken off under the weight of the give load.This paper treats the mini-truck of Changan Automobile works as the research object.discuss how to adopt FEM to simulate the fasten point inensity on the safe belt and finally gives a usable calculated model,boundary conditions and optimization design methods.
