摘　　要：通过分析常规游梁式抽油机四杆机构的6个传统设计变量对最大扭矩因数及最大加速度的灵敏度,确定了各设计变量对两个目标函数的影响程度.以灵敏度值较大的设计变量作为设计变量,用遗传算法对抽油机的四杆机构进行优化.优化结果表明:通过对灵敏部件尺寸的修改,抽油机的性能指标有了明显的改进.Sensitivity analysis on four-bar mechanism of travel-beam pumping unit is carried out in this study.The sensitivity of the 6 traditional design variables of the four-bar mechanism on the maximum torque factor and acceleration is analyzed.The effects of the design variables on the two object functions are determined.The variable with larger sensitivity value is selected as the main design variable in this study,and a genetic algorithm（GA）is adopted to optimize the four-bar mechanism of beam pumping.The results show that the performance indexs of beam pumping are improved obviously as the result of modifying the sizes of sensitive parts.
