摘　　要：论述矿用挖掘机在等后角挖掘时的推压-提升速度比及瞬时提升力的电算方法并提供了电算程序。依据该程序可确定任意挖掘位置时的提升力,亦可按挖掘机特定工况计算提升力的大小。解决了挖掘机总体设计中主要特性参数计算问题。The computation method of crawd-hoist spe-ed ratio and the instantaneous hoisting forceof mining excavator during constant returnangle excavation is described and the computerprogramme is presented. The hoisting force inany digging position can be determined by theprogramme and can also be calculated accord-ing to any special operating condition, so thatthe problem of major parameters calculation inoverall excavator design can be solved.
