| 摘 要： | 凸肩(叶冠)叶片及其盘组件的振动特性、振动响应及其减振效果的理论分析和实验研究均需要准确确定其摩擦接触边界条件。通过从Oden非线性、非局部摩擦定律出发,分析了它的机理和运动规律,并用试验方法测定了这些参数。所得结果不仅可用于理论分析建模,还可直接应用于工程设计、实验研究和生产检验。

| Abstract: | The theoritical analysis and experimental investigation of the intermediate shrouded blades and blade -disk assemblie on vibration characteristics,dynamic response and the effect of damping all have to accurately define the frictional contact boundary condition on shroud interfaces. The investigation on its mechanism and motion law are summarized with the non - linear and non - local law of O' den. Some parameters are measured in the experiments. The results of investigation can be used for theoretical analysis and engineering design, also can be used for-manufacture inspection. |
