Investigation on Damping Characteristics of Double Chamber Hydro-Pneumatic Suspension Simulation and Experimental Research

Abstract:

As to the optimization of double chamber hydro-pneumatic suspension,we researched the influence of excitation signal on the the damping characteristics. First of all, the double chamber hydro-pneumatic suspension nonlinear mathematical model and simulation model were set up to get the damping characteristic curves of different sources.And the influence of different factors was obtained according to the orthogonal test method. The results of the study show that the hydro-pneumatic suspension have nonlinear variable damping characteristics,the excitation signal with higher frequency and larger amplitude have superior damping effect;and the speed of the excitation signal have the biggest influence on its performance.The order of the influence of frequency (f), amplitude (A) and velocity (ν) to suspension performance is: ν>f>A.
