Purpose The shock absorber is an important component of vehicle suspension that attenuates the vehicle vibration. Its running state directly affects the performance of the vehicle suspension. The purpose of this paper is to quantitatively study the relationship between damping characteristics and air chamber and oil properties in single-tube pneumatic shock absorber. Design/methodology/approach Combined with the principle of fluid dynamics and hydraulic transmission technology, the rebound stroke and compression stroke mathematical models, and damping characteristics simulation model are established to investigate the effect of the air chamber and oil property on damping characteristics. Findings Research results show that the initial pressure of the air chamber is the key parameter which influences the damping characteristics of the shock absorber. The change of the initial pressure has more impact on damping force, and less impact on the speed characteristic; the initial volume of the air chamber almost has no effect on the damping characteristics. The density and viscosity of the oil have certain influence on the damping characteristics. Therefore, selecting suitable damping oil is very important. Originality/value Using Matlab/Simulink software to build simulation models, its results are very accurate. The conclusions can provide a theoretical reference for the structure design of a single-tube pneumatic shock absorber.

The article describes a method for calculating the speed characteristics of a single-tube hydro-pneumatic shock absorber developed by the author based on the use of basic approaches to the calculation of damping hydraulic systems. A regressive type of characteristic is substantiated in relation to the operating conditions of a specialized vehicle in urban conditions. There has been performed calculation and analysis of the speed characteristics of the hydro-pneumatic shock absorber proposed for use on Ford Transit ambulances.

The article describes the developed methodology for calculating the parameters of a single-tube hydropneumatic shock absorber. The calculation procedure is presented including calculating the volume of the gas filling cavity, calculating the parameters of the gas and the working fluid, determining the energy intensity of the shock absorber, checking the possibility of cavitation in the operating modes, as well as calculating the strength of the shock absorber parts.. A comparative analysis results of the calculated characteristics and the experimental characteristics of the hydropneumatic shock absorber are presented, the absorber having been produced according to the obtained design parameters. Based on the analysis, recommendations are given to increase the running smoothness of the car by replacing the standard hydraulic shock absorbers with hydropneumatic ones, taking into account the selection of the throughput of the discharge valves.
