翻滚安全性研究方法综述

首先对翻滚事故的分类、场景特征进行了归纳总结,然后从整车翻滚安全性试验方法、翻滚试验与翻滚事故场景的关联性、翻滚数值模拟方法等几个方面,对翻滚安全性的研究现状进行了阐述.目前研究认为,绊翻、抛翻、坠翻是发生比例最高的几类翻滚事故,绊翻试验(路缘绊翻及沙地翻滚)、螺旋翻滚试验、边坡翻滚试验方法能够覆盖大部分的翻滚事故场景.最后,分析了目前国内该领域研究存在的问题,未来还需在建立完整详细的翻滚事故数据库、形成科学合理的翻滚试验方法与规范、实现翻滚全过程的精细化数值模拟能力等方面加强研究.

Review on Research Methods of Rollover Safety

Firstly, the classification and scene characteristics of rollover accident were summarized. Then, the development of the rollover safety study was introduced in various aspects, such as the rollover safety test methods, the relevance between rollover safety tests and rollover accident scenes, and the rollover safety numerical simulation methods. The current conclusions were that trip-over, flip-over and fall-over were the dominant rollover accidents, and Curb-trip, Soil-trip, Corkscrew and Embankment rollover test methods could reflect most of the rollover accident scenes. Lastly, the current problems of rollover safety were analyzed, and and there is a need to strengthen the research in establishing a complete and detailed rollover accident database, forming a scientific and reasonable rollover test method and specification, and realizing the refined numerical simulation capability of the whole process of rollover in the future.
