Evaluation of possibility for recovering of energy from the suspension using air shock absorber

The evaluation of possibility for recovering of part of vibration energy from automobile has been done in the article. One of the potential possibilities is utilization of fluid pressure in shock absorber to drive turbogenerator applying battery. It can be interesting to utilize air shock absorbers, in Gerard to possibility of direct outlet of expanded air into atmosphere – it can simplify the design of set recovering energy. The aim of researches presented in the article has been to evaluate possibility for recovering of energy from air shock absorber without deterioration of vibration damping level, which can be provided by hydraulic shock absorber. The scheme of proposed air shock absorber, its mathematical model, the results of calculation for pressure increasing in shock absorber during its piston motion, for different velocity of the piston have been shown in the article. The characteristics of hydraulic absorber and air one with energy recovering have been compared. The model of the wheel and the automobile mass connected with that wheel has been presented. Using such model the simulations of the wheel and of the automobile mass motion, for tasked velocity of automobile have been made. The model of road microprofile has been elaborated.. Using the models the recovered energy in the 1 km road section has been calculated.
