附加气室容积可调空气悬架系统的决策控制

In order to improve vibration absorption performance under different driving patterns, the dynamic mode of quarter vehicle in non-linear system was built and the optimized analysis and calculating method for air suspension with adjustable volume of auxiliary chamber were presented to design air spring of adjustable stiffness and the decision-making control system of air suspension. On the basis of the simulation calculating, bench test of adjustable stiffness of air suspension was conducted, the dynamic characteristics of suspension system after using decision-making control was analyzed. The results of simulation calculating and experiment result were consistent, the function of real-time change volume of auxiliary chamber according to driving patterns was achieved.The study verified the effectiveness of control strategy and it provided a new method for developing the air suspension of adjustable stiffness.
