牙轮钻机稳定性分析及其CAD

Tunnelers & Excavators Analysis to Stability of Rotary Drill Rig and Its CAD

对牙轮钻机在露天矿山穿孔作业时的稳定性问题进行分析，建立了钻机的几种可能运行方式的力学模型，利用Visual LISP编制了稳定性分析的程序，并给出了应用实例。

The paper makes analysis to stability of rotary drill rig while it works in opencast mine, founds several dynamic model for possible running style of drill. In addition, and program for stability analysis has been developed by with Visual LISP and a case is offered at last.
