多功能三人座椅与车身强度匹配探究及应用

Research and application of strength matching between multi-functional three person seat and body

针对安全带固定点强度试验一次性通过率低的问题,提出通过改善多功能三人座椅与车身强度匹配性能以提高相关车型过法规一次性通过率。将已量产的4款M1类车型作为分析对象,基于GB 14167—2013,建立了单体座椅强度、整车强度和车身强度有限元模型,对比仿真及试验结果,探讨影响座椅与车身强度匹配性能的关键参数,并据此建立了座椅与车身强度的评价标准。将探究成果应用于新车型的研发上,且新车一次性通过安全带固定点强度试验。

In view of the problem of low passing rate of belt anchorage strength test, proposed to improve the passing rate of relevant vehicles through improving the strength matching performance of multi-functional three person seat and body. Four types of Ml vehicles produced were taker as an analysis object. The single seat strength, vehicle strength and body strength finite element model were established on the GB 14167-2013. Then,the key parameters which affect the strength matching performance of seat and body were discussed emphatically, and the evduation standard of seat strength and body strength was established according to the simulation and test results. The research results were applied to the development of new models and the new car passed through the strength test of the seat belt anchorage in one time.
