摘　　要：为了优化钻机底座结构以适应极地超低温下的工作环境,利用CATIA对钻机底座进行三维建模并将模型数据导入ANSYS Workbench中,结合极地环境条件因素,分析获得了钻机底座在临界载荷下的形变云图。根据云图找出底座结构薄弱点,对其结构进行初步改进,最后利用ANSYS中的拓扑优化功能对底座结构进行了改进设计,从而降低钻机底座在工作时的形变量,对确保其在低温环境中的使用寿命有设计指导意义。In order to optimize the structure of the rig substructure at extremely low temperature in the polar region,the three-dimensional modeling of the substructure was first carried out by using CATIA,and then the model data was imported into ANSYS Workbench to analyze the deformation of the substructure onthe critical load under the conditions of polar region.According to the cloud map,the deficiencies of the structure would be found and improvement of the rig substructure would be achieved.The structure optimization of the rig substructureis proposedbased on the ANSYS topology optimization,thereby reducing the deformation of the substructure at work and ensuring the duration of work in extreme low temperature environment.
