摘　　要：油田管柱排放作业劳动强度大、重复性强,钻台机械手能够实现管柱在操作平台和排放架之间的移送操作,可有效提高作业效率,降低劳动强度。针对大臂旋转移送型钻台机械手,从结构优化设计角度,开展其立柱总成的轻量化设计工作。综合应用参数化设计、灵敏度分析、NSGA-Ⅱ等方法,对立柱总成的结构尺寸进行了优化设计。研究发现:后部支撑钢板的厚度对结构的变形及应力响应影响最大,结构变形及应力随着其厚度的增加而显著降低,厚度增加到15mm时,结构的性能趋于最优状态。通过轻量化设计,实现立柱总成减重27.19%的同时,提高了立柱总成的力学性能,为钻台机械手的技术开发提供了理论支撑。Oilfield pipe string discharge operation has high labor intensity and repeatability.The manipulator on the drilling floor can realize the transfer operation of tubing and tubular tools between the operation platform and the discharge rack,which can effectively improve the operation efficiency and reduce labor intensity.In this paper,the lightweight design of the column assembly is carried out from the perspective of structural optimization design for the large arm rotary transfer type drilling table manipulator.The parametric design,sensitivity analysis and NSGA-II methods were applied comprehensively.It is found that the thickness of the rear support steel plate has the greatest influence on the deformation and stress response of the structure,and the structural deformation and stress decrease significantly with the increase of its thickness.Through the lightweight design,the weight of the column assembly was reduced by 27.19%while the mechanical properties of the column assembly were improved,which provided theoretical support for the technical development of the drilling floor manipulator.
