Abstract
Modern automotive shock absorbers, hydraulic shock absorbers are used. It uses liquid in the shock absorber through a number of small pores when the flow resistance, Body and frame to absorb vibration energy, the rapid elimination of vibration. Inflatable hydraulic shock absorber in the double-hydraulic shock absorber developed on the basis, double hydraulic shock absorber fully inflated double-hydraulic shock absorbers to maintain the structural form, and compression stroke recovery journey with the general principle of the same double-hydraulic shock absorber. There are low-pressure gas as a result of filling in the shock absorber in the course of its work to establish some form of back pressure, effectively improving shock absorbers of anti-distortion characteristics of the critical speed, the shock absorber to improve the performance, so that traffic safety and comfort to be better coordinated. In this paper, the main work is the vehicle shock absorber of the existing full investigation on the basis of the vehicle shock absorber characteristics of the analysis, design and calculation parameters to choose, combined with practical, conduct by hydraulic Structural design earthquake.
