摘　　要：为了降低翻滚事故对乘员的损伤,本文通过对交通事故统计分析研究,总结了发生翻滚事故的典型工况并对其适用场景进行了分析。通过将多体动力学与碰撞仿真相结合对翻滚后车辆的变形情况进行了分析和试验验证。结果表明:将两种方法相融合进行翻滚分析是有效的,同时车内乘员表现较好。翻滚保护的分析研究为国内外行业标准法规的制定提供了借鉴和参考。In order to reduce the harm caused by rolling accidents to human beings, this paper summarizes the typical conditions of rolling accidents and analyzes their applicable scenarios through the statistical analysis of traffic accidents. By combining multi-body dynamics and collision simulation, the deformation of rolling vehicle is analyzed and verified by experiments. The results show that the combination of the two methods is efective for rollover analysis, and passengers performance is very well. The analysis and research of rollover protection provide reference for industry standards and regulations at home and abroad.
