摘　　要：为了简化建立PDC单齿与岩石互作用模型的繁琐过程,提高PDC单齿破岩仿真的分析效率,使用Python语言和ABAQUS GUI建立了PDC单齿破岩仿真插件。该插件实现了PDC单齿结构参数、切削深度、前倾角和侧倾角的参数化建模;自动完成网格划分、边界条件定义、材料定义;后处理中结果输出及数据储存的功能。最后对仿真结果的合理性进行分析与对比,验证了使用该插件建立PDC单齿切削模型的正确性,为研究PDC单齿破岩性能提供了一个便携高效的分析平台,并为ABAQUS二次开发在其他领域的应用提供了借鉴。In order to simplify the complicated process of establishing PDC cutter/rock interaction model and improve the analysis efficiency of PDC cutter rock breaking simulation,the plug-in for PDC cutter rock breaking simulation was developed by using Python language and ABAQUS GUI.The plug-in implements parametric modeling of PDC cutter structure parameters,cutting thickness,rake angle and side angle,and automatically finishes meshing,boundary condition definition,material definition,post-processing result output and data storage.Finally,the rationality of the simulation results is analyzed and compared,and the correctness of the PDC cutter cutting model established by the plug-in is verified.The plug-in provides a portable and efficient analysis platform for the study of the PDC cutter rock breaking performance.The development of the plug-in also provides a reference method for the application of ABAQUS secondary development in other fields.
