【摘要】 在满足抽油机工作能力条件下， 以耗材最少为目标， 对游梁进行优化设计是降低抽油机成本的一个重要方面。以ＣＹＪＹ１０ —３ —５３Ｂ型游梁抽油机为例， 在游梁杆件长度已定的条件下，以等截面游梁横截面积为目标函数， 在强度约束条件下， 选取游梁上下板厚度、腹板厚度、截面宽度和截面高度四个独立参数为设计变量， 分别建立了箱形等截面游梁和工字形等截面游梁的优化设计模型。通过优化计算， 确定了箱形等截面游梁和工字形等截面游梁的截面尺寸参数。在同样满足抽油机工作能力条件下， 采用工字形等截面游梁比箱形等截面游梁节省钢材１３ ％ 。更多还原

【Abstract】 Under the condition of meeting the working requirements of pumping units, aimed at lest material consumption, the walking beam is optimized. By taking Model CYJY10-3-53B beam pumping unit as an example, assuming that the length of the beam is given, by taking the cross area of uniform section beam as objective function and selecting four independent parameters as design variables, the models for optimization of both box shaped and Ⅰ shaped uniform section beams are established, and corresponding section sizes are determined. It is concluded that the walking beam with Ⅰ shaped section requires less material than that with box shaped section.更多还原
