前排座椅安全带固定点强度仿真分析及优化

The Strength Analysis and Structure Optimization of Seat Belt Anchorage for Front Seat

以公司某款乘用车前排安全带固定点为研究对象,通过有限元方法建立模型,对法规试验进行仿真分析。依据分析结果进行结构优化,提高安全带固定点强度,满足法规要求。同时针对安全带固定点计算模型经常出现的计算中断问题进行优化,并利用CAE分析技术在产品开发过程中的应用,有效找到问题原因并有针对性地加以优化,从而缩短开发周期和节约成本。

The front seat belt anchorage of a vehicle is taken as the object,the model is built by finite element method,and the case of the regulation is simulated.According to the analysis results,the structural optimization is carried out to improve the strength of the seat belt anchorages,which can meet the regulation requirements.Meanwhile,the calculation interruption problem that often occurs in the simulation process is optimized.Through the application of CAE analysis technology in the product development process,the cause of the problem can be found effectively and optimized in target,thus shorten the development cycle and save costs.
