摘要
通过评价单目标函数各自特点，提出了以多目标来优化抽油机的几何参数，并运用了单目标自动寻优与多目标综合判优的策略。建立数学模型时优选了约束条件，消除了不起作用的约束，使运算速度加快，经过对ＣＹＨ１２－４．８－７３ＨＢ型抽油机的计算，优选出一组最优设计方案，与现有同类型抽油机相比，最大扭矩因数和最大悬点加速度均减小，整机重量减轻。
After an evaluation of the characteristics of each single-opjective function, it is Put forward to optimize the geometric parameters of a pumping unit with multi-objectives, and the method of single-objective automatic searching and multi-objective comprehensive decision is used The constraint conditions are optimized in establoshing the mathematic model, resulting in higher computing speed.By the above-mentioned method, the design of Model CYJY12-4.8-73HB pumping unit is optimized.The result shows that both the maximum torque factor and the maximum polished rod acceleration of the optimized unit are decreased and its weight is reduced.
