【摘要】 本文分别以抽油机上冲程悬点最大加速度及最大扭矩因数为目标函数,优化设计抽油机各杆件的几何尺寸,以曲柄轴净扭矩的均方根值为目标函数,优化设计平衡重的滞后角。优化设计的异相平衡抽油机具有较好的动力特性及显著的节能效果。更多还原

【Abstract】 Taking the highest acceleration and the bigges torque factors as the objective function, the author of this paper has optimized the geometricalt dimensions of some longer and thinner parts of pumping units. Taking mean square root of the net torque of the crankshaft as another objective function, the author has optimized the lagging angle of the balance weight. The optimized pumping units are characterized with better dynamic features and excellent power-saving.更多还原
