摘　　要：确定了起动机保险轴的断裂性质;对保险轴的特性和承载能力进行分析。验证试验表明不平衡量为0.9 g/cm的涡轮转子无法导致保险轴断裂。最终得出保险轴断裂性质属于符合设计意图的正常断裂的结论。The broken character of safety spindle was defined. The character and carrying capacity of the safety spindle was analyzed. The turbine-rotor with 0.9 g/cm non-counterbalance can not result in the safety spindle broken. The conclusion of fault analysis is that the safety spindle broken character is normal broken according with design intention.
