摘　　要：提出对常规抽油机的四杆机构进行节能改造的设计方案,并建立优化数学模型,采用遗传算法对四杆机构进行优化。模拟实际工况对CYJ8-3-48HB型抽油机四杆机构进行优化,程序简单,易于实现。通过改造前后的结果对比表明:改造机的运动、动力性能得到了明显的改善,有功功率下降21.08%,节能效果好。The mathematics model of the four-rod mechanism of beam-pumping unit by changed it＇ s length in order to achieve energy-saving are Building, and optimized it＇ s structure by using genetic algorithm. The actual calculation of the CYJS-3-48HB model under the field condition shows that method is simple and feasible, the property of motion and dynamic has been greatly improved ,the active powder decreases by 21.8%, and the energy saving effect is obvious.
