摘　　要：针对双级摇臂大采高短壁采煤机机身短、重心高、稳定性差的问题,基于采煤机与输送机的配套数据,确定双级摇臂大采高短壁采煤机的重心分布。建立采煤机的静态工况和动态工况下的横向稳定性模型,确定其临界失稳条件。在此基础上提出了改善采煤机整机稳定性的技术措施。In view of the problems of short body,high center of gravity and poor stability of the two-stage rocker arm high mining height short wall shearer,based on the supporting data of the shearer and the conveyor,the center of gravity distribution of the two-stage rocker arm high mining height short wall shearer is determined.The lateral stability model of shearer under static and dynamic conditions is established to determine its critical instability conditions.On this basis,the technical measures to improve the stability of the shearer are put forward.
