摘　　要：以矿用防爆液压提升机制动系统为对象建立其故障树模型,运用蒙特卡罗法对制动系统关键部位可靠性进行仿真分析。实际使用情况及仿真结果表明,在防爆提升机液压制动系统中采用基于故障树的可靠性仿真分析,能够提高可靠性分析精度,发现制动系统的薄弱环节,为制动系统维修提供科学依据。The fault tree model of the brake system of explosion-proof hydraulic hoist was built. The reliability simulations about main parts of the brake system were made based on Monte Carlo analysis. Practical application and simulation results indicate that in the brake system of explosion-proof hydraulic hoist,using reliability simulation based on fault tree model can enhance the precision of reliability analysis, find out the weak link.This method can provide reference for the maintenance of the brake system.
