A Review of Aeration and Cavitation Phenomena in the Hydraulic Shock Absorber
Applied Mechanics and Materials, 2014This paper aims to bring an organized overview of the damper malfunction due to the cavitation and aeration phenomena, which are normal problems for all kinds of hydraulic dampers. The object of this report is to describe, detect and simulate these damper failures.

The Effects of the Aeration Phenomenon on the Performance of Hydraulic Shock Absorbers
2021This work introduces a method, based on the DOE experiment, for assessing the risk of negative aeration by obtaining an experimental measure, which was further correlated with a theoretical gas concentration measure intended for mono- or twin-tube hydraulic shock absorber models.

Damping-force control mechanism in a hydraulic shock absorber
The Journal of the Acoustical Society of America, 1980A damping force control mechanism in a hydraulic shock absorber having a piston disposed within a cylinder casing so as to define a pair of hydraulic chambers. A plurality of ports are formed through the partition to enable passage of hydraulic fluid between the hydraulic chambers and an orifice plate mounted on the partition enables stepwise rotation ...

The dynamic performance of automotive vehicles is influenced by the suspension system design. Suspensions owing damping elements with a wide range of non-linear behaviour can provide higher mobility and better ride comfort performances. Pneumatic suspensions due to their inherent nonlinear behaviour can provide high mobility performance while ...

Analysis of the deflection of reeds in automotive hydraulic shock absorbers
Chinese Journal of Mechanical Engineering (English Edition), 2000The deformation of reeds in automotive hydraulic shock absorbers is analyzed with the finite element method. Combination of different thick reeds mounted on different supports is studied. The computational results show that deformation of the overlapped reeds is not always equal to the sum of deflection of single reed under any conditions. Experimental

The Effects of Fluid and Mechanical Compliance on the Performance of Hydraulic Shock Absorbers
Journal of Engineering for Industry, 1974Dimensionless differential equations are developed which model a hydraulic shock absorber. These equations are solved numerically to determine quantitatively the effects of fluid compressibility and series and parallel springs on the shock absorber operation.
