密栅云纹检测法在水力机械制造中的应用

An Application of the Fine Moire Pattern for Blade Measurement in Hydraulic Machinery

本文介绍了一种利用光学干涉原理检测水力机械叶片的新方法,即密栅云纹法。文中还介绍了该方法在轴流式模型转轮叶片上的应用,并获得了满意的结果。

A new method for measuring runner blades of hydraulic machine, known as the fine moire pattern, based on principle of optical interference is introduced. And an application of this method for measuring of the model runner blade of axial type is also presented, and the results of measurement are satisfactory for use.
