Abstract
Aiming at the phenomenon of bending deformation caused by the pressure difference of the throttle plate in the working process of the damping valve, the analytical calculation of the large deflection of the annular thin plate was carried out. On the basis of extracting the physical model of the thin plate, the boundary conditions and initial conditions of the annular thin plate were set by using the Qian’s perturbation method, and the nonlinear large deflection deformation analytical formula was derived; Through the finite element modeling, the accurate numerical solution of thin plate deformation was obtained, and the key parameters of the analytical formula were corrected by the least squares method. Through verification, the modified analytical formula had the characteristics of easy calculation and high calculation accuracy, and the influence law of the large deflection of the throttle valve was studied, which provided the necessary theoretical support for the accurate design of the damping valve performance.
