Bending Deformation and Coefficient of Throttle-Slice

A mechanical model of elastic ring throttle-slice is established and the differential equation of deformation is set up.With the boundary conditions,the general solution for the deformation of elastic throttle-slice is obtained.Deformation coefficient（G_r） and expressions are obtained by identically transforming the general solution.On this basis,a precise computation method for the deformation of throttle-slice at any radius r is put forward.On comparing the coefficient（G_r） with the flexibility coefficient（C₆） by a computation of maximum bending deformation,it is shown that the computation with bending deformation coefficient（G_r） is more precise than that with the flexibility coefficient（C₆）.
