Abstract:Based on differential geometry theory, the nonlinear system was transformed to a linear one, and the linear feedback control system of semi-active connected hydro-pneumatic suspension was done. With the software AMESim and MATLAB/Simulink, the co-simulation model of semi-active connected hydro-pneumatic suspension was completed. The simulation results show that the semi-active connected hydro-pneumatic suspension improves the property of upper vehicle, which decreases the stable time of instantaneous impact and the maximum values of instantaneous impact and enhances the ability of vibration damping and overturning resistance. Moreover, it improves suspension dynamic flexibility, which makes the suspension vibrate more smoothly and reduces the instantaneous vibration intensity. ? 2016, China Mechanical Engineering Magazine Office.
