摘要
本文以空间解析几何的数学理论,推导出了三牙轮钻头瓢形齿的横截面积、体积与瓢形齿吃入岩石深度之间的数学关系式,为研究钻头牙齿破碎岩石坑的形状大小提供了基准,也可作为三牙轮钻头工作行为计算机仿真研究的参考资料。
According to the mathematical theory of analytical space geometry, the paper has established the mathematical relationship between the sectional area and volume of the scoop-shaped tooth of three-cone bit and the depth of tooth penetrating rock. The mathematical relationship has provided the standard for the study of the size of bit teeth breaking rock, laid the foundation for the computer imitation of three-cone bit, and provided the unprecedented reference materials for the people working on bit research as well.
