摘要：超级电容车是我国新能源战略的一个重要举措.它在上海世博会上投入使用的意义重大,保障其运行安全性显得尤为重要.对于传统安全性分析方法,FTA缺乏对事故动态性的描述能力,同时在对事故定量分析方面存在局限性;ETA在对复杂系统安全性分析上亦有局限.而利用GTST-MLD模型和Petri网模型各自的优势对电容车进行安全性分析,建立GTST-MLD和Petri网模型之间的基本符号、基本类型和事故演化路径相互转化的桥梁,进而将两种方法进行集成.这样不仅对安全事故演化能给出定性描述,同时融入事故演化过程的时间等因素,给出更为准确的定量评估数据.
Application of the super capacitor automobiles in a safe operational condition is significant and necessary, which has been a new energy strategy in China. As the traditional methods of safety analysis, FTA has no ability to describe dynamics and quantitative analysis of the accident, while ETA is restricted by the safety analysis of complex systems. This paper builds bridge for conversion between GTST-MLD and Petri net, for example, basic symbol, base type and 5 evolution routes of accident. The integrated approach is not only qualitatively describes the evolution of safety accident, but also combines with other factors such as time and probability of the evolutionary progress, and provides a more accurate quantitative result of safety assessment.
