以深孔立轴岩心钻机深孔钻进启动时离合器为研究对象,建立离合器接合过程动力学模型,利用MATLAB编程求解微分方程数值解,研究了离合器操纵、启动挡位和钻孔深度等因素对接合时间、滑摩功率、滑摩功等接合过程参数的影响。研究发现：随着钻孔深度的增大离合器接合时间延长,滑摩功线性增大。挡位传动比对离合器从动部分的等效转动惯量、等效阻力矩影响大,对于特定钻机可以在500米以浅采用二挡直接启动。

The purpose of this paper was to study the clutch engagement process dynamics for deep core drilling rig, a dynamics model for clutch engagement process was built up and MATLAB pro- gramming was used to solve differential rotating equations. Clutch manipulation, gear and drilling depth will affect engagement time, slipping power, and friction work. It is shown that the deeper the drilling hole, the longer the clutch engagement time. As the drilling depth increases, the friction work increases linearly. Gear transmission ratio will affects the moment of inertia and the moment of mud damping force and bit cutting surface resistance greatly. For a specific rig it can start in second gear within 500m.
