Numerical Analysis and Graphic Display for the Motion Diagram of water Turbine Radial Guide .Apparatus

本文用数值分析方法研究了非标准系列径向式导水机构的运动关系,论述了如何由计算机绘制相应的图形.为此,建立了导叶翼型及传动机构的数学模型,选定了合理的数值计算方法,进行了程序设计和调试,从而开发出径向式导水机构运动图的CAD软件.

The motion diagram of a guide apparatus is one of the important diagrams in water turbine design. The motion relation of non-standard series of guide apparatus is studied by numerical analysis. The method of drawing the diagram with a computer is discussed cubic spline function interpolation is used to fit the curve profile of guide vane and the Newton iterative method is used to calculate the value of .After some required parameters with different openings ahave been calculated and rotation transformation carried out on profile coordinates, the motion diagram of the guide apparatus can be drawn by a computer with the programs developed by the authors.
