| 摘 要： | 讨论了一种新型单牙轮钻头——异形牙轮单牙轮钻头。在钻头几何学和运动学的基础上，通过坐标变换方法实现了钻头上各牙齿的空间位置变换，建立了随钻运动的单牙轮钻头的计算机仿真模型。仿真模型可模拟钻头钻进过程中牙轮上各牙齿的形状、大小、钻头上各牙齿的布置及钻头钻进过程中各牙齿间的相互位置关系，是钻头与岩石相互作用仿真研究的核心问题，也是分析研究单牙轮钻头工作行为的基础。

| Abstract: | A singular one-cone bit is designed. The space position shift of teeth is realized by means of coordinate shift. Based on the geometry and kinematics of one-cone bit, the computer simulation model of a singular one-cone bit is set up which can actually reflect the shapes, sizes and the relative position of the teeth on bit during the bit drilling process. The study is one of the key problems of simulation research of bit-rock interaction as the foundation of analyzing the working behavior of one-cone bit. |
