| Abstract: | 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. |
