摘　　要：以某矿现有旋转钻机为研究对象,运用有限元分析软件ANSYS WorkBench对钻杆进行了受力分析及参数优化,获得了钻杆质量最小时钻杆轴内径和螺旋叶片厚度值。运用ADAMS软件建立了钻杆钻进系统刚-柔体模型,通过对钻进过程的运动仿真,得到了钻杆在钻进工作中的接触及变形情况,并分析了钻杆完全钻进过程中的屈曲行为。研究结果为钻机的改进及钻进效率的提高提供了理论参考。Taking a mine field existing rotary drill as research object,using the finite-element analysis software ANSYS WorkBench to carry out force analysis and parameter optimization of drill pipe,obtain the inside diameter of drill pipe shaft and thickness values of the spiral blade under the condition of quality minimum of drill pipe.The rigid-flexible body model for drilling system was set up by using ADAMS software,through the motion simulation acquire contact state between drill pipe and hole wall and the drilling track of drill pipe,and analyze the deformation and buckling behavior of drill pipe.The results of the study provide a theoretical reference for the drill improvement and drilling efficiency increased.
