摘要： 针对传统的断裂力学和疲劳强度分析方法在起重机械主梁安全性评估中存在考虑因素不全面的问题,提出了故障树分析和蒙特卡罗仿真技术相结合的方法对起重机械主梁进行可靠性分析.以某起重机主梁为例,通过故障树分析建立了主梁的失效模型,应用蒙特卡罗抽样对其可靠性进行了仿真计算,结果证明了该方法的可行性与有效性,为起重机械主梁的可靠性分析和安全性设计提供了一定的借鉴和参考.

Abstract: The traditional analyzing methods of fracture machanics and fatigue strength have the disadvantage of neglecting some factors in the safety design of the crane girder. This paper proposes to combine the Monte Carlo method and the fault tree analysis to study the reliability of the crane girder. Taking a certain crane girder as an example, we build the failure model according to the fault tree analysis and then simulate the reliability by using Monte Carlo method. The results confirm the feasibility and efficiency of this method that provides a reference for the reliability analysis and the safety design of the crane girder.
