摘　　要：多股螺旋弹簧(简称多股簧)加工参数对其成品质量耦合作用机理研究尚不完善,导致多股簧加工合格率低、推广难度大,为此提出一种优选多股簧工艺参数的实验方法。基于二分法获取满足多股簧刚度要求的拧索螺距;采取实验设计方法设计了芯轴直径、弹簧螺距和钢丝张力3个工艺参数的优化实验,通过信噪比均值分析得到最优多股簧加工参数组,并通过钻杆复位多股簧实际生产对该方法进行了验证。研究结果表明:优选多股簧工艺参数的实验方法切实可行,可以减少多股簧制造加工参数获取时间,节约多股簧工艺研究成本,为我国武器装备质量的提升提供参考。The research on the coupling mechanism of the processing parameters of stranded wires helical springs(SWHS)for the product quality has been incomplete,which leads to the low yield of SWHS and the difficulties in large-scale promotion.An experimental method for optimizing the processing parameters of SWHS is proposed.The dichotomy method is utilized to obtain cable pitch,which is proved to meet the stiffness performance requirement of SWHS.The optimization experiments of three processing parameters,including mandrel diameter,spring pitch and wire tension,are designed based on DoE method.An optimal SWHS processing parameter group is obtained by means of the mean analysis of signal-to-noise ratio.The practical processing of reset SWHS for drill pipe proves that DoE method is feasible.The research results show that the DoE method can be used to reduce the acquisition time of processing parameters of SWHS,and save a lot of costs for the research on SWHS processing technology.
