摘要

摘要: 以提升机制动系统制动力不足故障作为具体研究对象，分析了提升机制动系统可靠度函数模型；通过相关性分析得出制动力不足故障的故障链，结合独立故障率和相关系数计算了考虑相关性的总故障率；分析了考虑相关性和不考虑相关性2种情况下的制动力不足故障间隔时间分布，线性拟合结果表明，考虑相关性的制动力不足故障间隔时间分布更符合威布尔分布模型。实验结果表明，故障率理论值与实际值的误差范围为1.33%～3.25%，验证了可靠度函数模型的正确性。

Abstract: Reliability function model of braking system of hoister was analyzed taking braking force failure as specific study object. Fault chain of the braking force failure was obtained by correlation analysis, and total failure rate considering relevance was calculated combined with independent failure rate and correlation coefficient. Time interval distributions of braking force failure in two cases of considering relevance and not considering relevance were analyzed, and linear fitting results show that the time interval distribution of braking force failure considering relevance is more consistent with Weibull distribution model. The experimental results show that the error range of theoretical and practical values of failure rate is 1.33%~3.25%, which verifies correctness of the reliability function model.
