The analytical equation is deduced using the plate theory according to the physical model of throttle slice, which is convenient for the theoretical analysis and engineering application. The equation is validated by finite element calculation results. The relation between different loads, structure parameters, materials characteristics of throttle slice and the deflections are studied. The analytical equation and conclusion offer some guidance to design throttle valve of shock absorber.
