摘　　要：针对长距离越野带式输送机运输线路复杂、输送带上物料分布不均匀等特点,利用 Belt Analyst 分析软件,建立了 5 种出现概率较高的工况模型,静态分析了这 5 种工况下带式输送机圆周驱动力、电动机轴功率、张紧力等参数的差异,确定了最恶劣工况。同时对带式输送机启动、停车和制动期间输送带关键点张力、滚筒合力、张紧小车位移和速度、驱动滚筒紧松边张力比等参数进行了动态分析,调整了最终滚筒合力参数。经过一年多时间的运行检验,该系统各项参数满足稳定运行要求,对长距离越野带式输送机设计具有一定的参考意义。In view of the features of the long-distance off-road belt conveyor such as complex delivery route and uneven distribution of material on belt,Belt Analyst software was applied to establish five models representing easily appeared operation modes,and the difference in such parameters as the circumferential driving force of the belt conveyor,the shaft power of the motor,tension etc.in the five operation modes were analyzed statically,and then the worst operation mode was identified.Moreover,the parameters such as the tension at key points of belt,the resultant force of the drum,the displacement and the velocity of the tensioning trolley,the ratio of tension at tight and loose side of the driving drum at the time of start-up,halting and braking of the belt conveyor were analyzed dynamically,and then the final resultant force of the drum was adjusted.After more than one-year operation,each parameter of the system met the requirements of stable operation,which was of certain reference significance for the design of the long-distance off-road belt conveyor.
