玻璃钢抽油杆疲劳性能的灰色预测

Grey Prediction to the Fatigue Properties of Fiber Sucker Rods

应用灰色系统理论对玻璃钢抽油杆的疲劳性能进行研究，建立了不同交变应力与对数循环次数之间的生成函数。

By using the theories of grey system,this paper discusses the fatigue properties of Fiber Sucker Rods(FSRs),and establishes the generating function between the alternating stress to the logarithmic cycle-index.Through the generating function, the fatigue limit of FSRs is predicted,and the result is good.
