Study on The Analytic Calculation Method of Throttle Slice Deformation

In this paper, the governing differential equation for deformation of a single throttle-slice is introduced first, and based on its solution satisfying required boundary conditions, the formula and coefficient for deformation of a single slice is obtained through equivalency transformation. The G_r and it´s physics meaning at different radius are studied, the deformation at any radius r is researched. At last, compared with other methods, such as machine design and ANSYS FEA software, the compared results show that G_r method is the most precise computation method way of throttle-slice deformation, and has very important meaning to the throttle-slice design, analysis, and verification, at the same time, it provides an effective method for mathematics theory better used in practical application.
