Model of the maximum design thickness of superposition throttle slices of shock absorber

The governing differential equation for bending deformation of a single throttle-slice was introduced first, and based on its solution satisfying required boundary conditions, the formula and coefficient for bending deformation of a single slice was obtained through equivalency transformation. Then, the formula for equivalent thickness of the throttle multi-slice, the stress coefficient and the thickness coefficient of slice were defined, the design model of the maximum thickness of multislices was got. Based on these, a new scheme for designing maximum thickness of multi-slices according to its nominal thickness was suggested. Followed was a practical example for design and stress analysis of a multi-slice throttle, together with its numerical simulation by ANSYS, and damping characteristic test. The compared results show that the design scheme of maximum thickness of multi-slices is effective and the formulas for equivalent thickness and maximum stress of the throttle multi-slices are accurate enough.
