Abstract
Purpose
The purpose of this paper is to study the influence rules of geometric parameters on deformation of valve slices.
Design/methodology/approach
Based on the theory of flexural deformation of elastic thin slice, differential functions of deformation for both single and multi-slices are given and derived in detail. Furthermore, the effects of geometric dimensions on deformation are analyzed particularly by using Matlab/simulink.
Findings
The results indicated that the deformation decreases with the increment of fixed ring radius ra, slice thickness h, and its number n. Meanwhile, the deformation increases with a rise of slice radius rb, throttle position rk, the radius ratio λ1 and thickness ratio λ2 of slices.
Originality/value
This research can provide some theoretical supports for the parametric and optimal design of adjustable damping shock absorber.
