    摘要:

    针对汽车安全带卷收器失效的问题,以复合紧急锁止式汽车安全带卷收器为研究对象,简介了 汽车安全带卷收器的工作原理和失效形式;通过分析汽车安全带卷收器失效的原因,提出解决汽车安全带卷 收器支架变形和芯轴断裂的结构优化设计方案;应用 HyperMesh 有限元软件分析,以轻量化为目标,分析了 汽车安全带卷收器结构的应力值和强度值,对比标准表明其结构满足使用性能要求,降低了后期制作样品的 成本,提高了其经济性和技术性,为汽车安全带卷收器设计提供参考。

    Abstract:

    Aiming at the problem of the failure of the automobile seat belt retractor, the composite emergency locking automobile seat belt retractor is taken as the research object, and the working principle and failure form of the automobile seat belt retractor are introduced. By analyzing the reasons for the failure of the car seat belt retractor, a structural optimization design plan to solve the deformation of the car seat belt retractor bracket and the fracture of the mandrel is proposed. Using HyperMesh finite element software analysis, with the goal of lightweight, the stress value and strength value of the automobile seat belt retractor structure are analyzed. The comparison standard shows that the structure meets the performance requirements, reduces the cost of post-production samples, improves economical and technical efficiency, and provides a reference for the design of car seat belt retractor.
