中文摘要: |
动力头作为岩心钻机中动力传递的核心部件,其性能好坏决定着钻探施工的工程质量与效率.根据目前地质勘探市场需求,对YDX-1200L岩心钻机动力头进行增扭设计,并运用有限元软件对动力头箱体在一档最大载荷情况下进行了静力学分析,在此基础上,选取侧壁厚度、固定拖板厚度等作为设计变量,在ANSYS Workbench进行多目标优化,在满足受力的情况下,减轻了箱体质量,为变速箱体设计及制造提供理论参考;其研究方法对其它类型箱体具有借鉴意义. |
英文摘要: |
Power head is one of the key parts of force transmissibility in core drilling process, its performance affects engineering quality and efficiency of the drilling. According to market requirements, torsion increasing design of power head for the YDX -1200L core drill was introduced. The finite element analysis approach was adopted to simulate the gear case when it was in the first gear with maximum load. On this basis, the thickness of the side wall and fixed dragging plate were chosen as design variables, and multi-objective optimization was used based on ANSYS Workbench, the weight of box body was reduced under the condition of meeting the stress. It provided the theory references for the design of gearbox and the study method would also be a reference for the design of other kinds of case. |
