摘要
在钻头几何学研究的基础上,通过坐标变换依次建立起了三牙轮钻头的牙齿、牙轮和钻头的计算机仿真几何结构模型;并在MATLAB编程语言环境下实现其数据的可视化,获得了他们的三维实体图形,包括其形状、大小和位置。结果表明MATLAB编程简单易写,结果正确可靠。该研究为在MATLAB环境下进行牙齿的运动仿真和钻头与岩石互作用仿真研究奠定了基础。
In this paper, a series of geometry simulation models were established by using coordinate transformation which included models of tooth, cones and whole bits based on the bit geometry study, and based on the visualization technology of MATLAB, three dimensions graphic of these models were gotten, including their shape ,size and location. The result shows that the MATLAB is a simple and compiled easily softawre, the output is accurate and reliable. This study provied a basic for motion simulation of teeth and interaction between bit and rock under MATLAB environment.
