单齿静压入实验破碎坑的数据处理及几何建模

GEOMETRIC MODELING AND DATA PROCESSING OF CRATERS FROM STATIC INDENTING TESTS BY SINGLE INSERT

单齿静压入实验是“牙轮钻头与岩石互作用仿真”课题的基础实验研究工作。西南石油学院钻头研究室针对四类岩石、三类不同冠部形状的硬质合金牙齿 ,进行了大量的单齿静压入实验。根据实验结果提出了三类牙齿静压入破碎坑的几何模型 ,并简要介绍了通过破碎坑实验数据的处理获取几何模型特征参数的方法。

Several groups of static indenting tests by single insert are introduced. The method of geometric modeling for the craters resulting from static indenting tests is important to computer simulation of rock bit penetrating and discussed through processing the data acquired from the tests.
