摘　　要：以典型的电梯鼓式制动器为研究对象,基于可靠性理论,对常见的“串-并联系统”和优化后“并-串联系统”的可靠性进行了推导计算。案例计算结果表明,在不增加和减少现有零部件且不提高原零部件本身可靠性水平的基础上,可通过合理的设计,仅改变零部件的组合方式,就可以提升整个系统的可靠性。In this paper,a typical elevator drum brake is taken as research object and based on the reliability theory,the reliability of the common"series-parallel system"and the optimized“parallel-series system”is deduced and calculated.The results of the calculation show that the reliability of the whole system can be improved by rational design and changing the combination of parts without increasing or decreasing the existing parts and without improving the reliability of the original parts.
