摘　　要：针对采煤机牵引机构长期运行情况下易受到损坏、可靠性不足的缺陷,提出了基于模糊可靠理论的采煤机牵引机构传动系统可靠性分析方案。建立了采煤机牵引机构动力学模型及采煤机的动态可靠性模型,对采煤机传动系统可靠性进行分析,结果表明,采煤机牵引机构传动系统工作时的动态可靠性随着工作时间的增加而逐渐降低,在工作时间达到600 h后,工作的动态可靠性就降低到了约0.994 6。In this paper,the paper presents a reliability analysis scheme for the transmission system of the shearer traction mechanism based on fuzzy and reliability theory,aiming at the defect that the shearer traction mechanism is vulnerable to damage and insufficient reliability under long-term operation.The dynamic model of the shearer traction mechanism and the dynamic reliability model of the shearer are established.The reliability of the transmission system of the shearer is analyzed.
