抽油机游梁的优化计算

Optimum Calculation for Walking Beam of Pumping Unit

指出了游梁式抽油机游梁优化设计计算的必要性,建立了数学模型,介绍了求解方法,并从制造和使用角度分析了游梁应采用的结构形式,提出了合理全面的边界条件和约束条件,并举例进行了优化计算。优化后材料比优化前节约8.7％,且强度、刚度、稳定性可靠,每年可为企业节约几十万元资金,经济效益十分可观。

This paper points out the necessity of optimizing design of walking beam of pumping unit, gives the mathematical modle, introduces calculating methods and analyses the walking beam structure from the manufacturing and operating view, sets up overall boundary conditions, constraint condition and gives the example, saved material 8.7%,but bending modulus is almost same.
