Hybrid modeling and verification of disk-stacked shock absorber valve

Abstract

The mathematical model of valve deformation of hydraulic shock absorber is established using the hybrid method of large deflection and beam deflection. The model can be used for design purposes and helps in developing damping valve based on single disk and shim stack. The model of the hydraulic shock absorber with valve system consists of shim stack and a spring preloaded disk is developed using AMESim. The correctness of the mathematical model of the valve deformation based on the hybrid method and the simulation model using AMESim is verified by the shock absorber bench test, which proves the method proposed in this article is reasonable and reliable. It is significant for reference in the design and development of hydraulic shock absorber.
