摘　　要：为了使轨道交通产品进入高安全要求市场,准确理解和综合运用故障树分析(FTA)、事件树分析(ETA)和危害树分析(HTA)方法,以及将这些方法与轨道交通产品的功能安全分析和认证要求相结合,是一个值得深入研究的重要课题。文章深入阐述和归纳了上述三种方法,并以某动车组空调系统通风和紧急通风功能为例,运用这三种方法进行功能安全综合评估与分析。In order to make rail transit products enter the market with high safety requirements,it is an important subject worthy of further study to accurately understand and comprehensively use the methods of fault tree analysis(FTA),event tree analysis(ETA)and hazard tree analysis(HTA),and to combine these methods with the functional safety analysis and certification requirements of rail transit products.This paper deeply expounds and summarizes the above three methods,and takes the functions of ventilation and emergency ventilation of air conditioning system for an EMU as examples to use these three methods for comprehensive evaluation and analysis of functional safety.
