样条函数在水力机械零件应力计算中的应用

Application of splint function to stress evaluation of hydraulic machinery components

以水轮机控制环的应力计算为例，采用样条函数方法从位移着手，通过求得控制环的线性位移来求得控制环所受的应力，并与传统方法计算所得结果进行比较，说明采用该方法的先进性和合理性。

Employing spline function to evaluate the displacement, the stress within the gate operating ring of water turbine can be predicted by means of determination of linear displacement of the gate operating ring. Comparing the evaluated results obtained by using the method presented with those obtained by using conventional method, the former is proved to be reasonable and advanced.
