摘　　要：为了研究刮板输送机运输不同物料时链环系统可靠度的动态过程,利用MATLAB编程并进行仿真分析,得到了圆环链的年龄分布规律和刮板链系统可靠度的动态变化过程。同时为了在保证刮板链系统安全性的基础上,尽可能的保证系统的经济性,即成本最低,对运输不同物料时系统所对应最佳维护周期进行了选取和仿真评估。仿真结果表明:当运输的物料为矸石、中煤、原煤和精煤时,系统的最佳维护周期分别为0.5个月、1.5个月、2.5个月和5个月,针对不同物料选择合适的维护周期可以很好的满足刮板链系统安全性和经济性的要求。To study the dynamic process of the reliability of the chain system when the scraper conveyor transports different materials, the programming and simulation analysis are carried out by using MATLAB. The age distribution law of the round link chain and the dynamic changing process of the scraper chain system reliability are obtained. Optimum maintenance periods of different materials are selected, and the simulating evaluations are made in order to ensure the economy of the scraper chain system, namely minimum cost, on the basis of ensuring the safety. The simulation results show that the optimum maintenance periods of the system is respectively 0.5 month, 1.5 month, 2. 5month and 5month when the scraper chain system transports materials are in sequence of the gangue, middlings, raw coal and clean coal. According to different materials, suitable maintenance periods are selected which can commendably meet safety and economic requirements of the scraper chain system.
