摘　　要：首次使用Matlab软件进行单牙轮钻头的计算机模拟仿真,通过矩阵变换得到牙轮模型,并绘制出楔形齿井底牙齿轨迹图,通过岩石破碎体积的计算,得到了异形牙轮与球形牙轮的牙齿轨迹在井底覆盖方面的比较。对牙轮及牙齿的设计有指导意义。The eomputer simulation is maken for one-cone bit by the first use of MATLAB software, cone model is got through the matrix transformation, and trajectory diagram of the wedge teeth is drawn. Through the rock crushing volume eah＇ulation, the comparison is obtained about situation of teeth trajectory covering the bottom of profiled-cone with spherical cone. The sig-nificance is provided to the design of cone and teeth.
