通过材料性能检测、金相组织检验和断口形貌分析，确定了索道吊架失效是疲劳破坏。用有限元的方法计算了整个吊架的应力分布，在此基础上用第二类疲劳图验证了索道吊架的失效模式。通过综合分析可以看出结构设计不合理导致了索道吊架的失效。

The analysis of materials and fracture appearance shows that thecracks on the hanger of ropeway are caused by fatigue failure. The stress state of the whole hanger is calculated by the finite element method. Then, the failure of the hanger of ropeway is also determined by the second fatigue chart. The conclusion is the improper design caused the failure of hanger of ropeway.
