Advance the stability of the vehicle by using the pneumatic suspension system integrated with the hydraulic actuator

The stability and comfort of vehicles depend on the operation suspension system. To increase smoothness for passengers in vehicle, stiffness system needs to be changed flexibly. conventional pneumatic can partially meet these requirements. However, change is not much. This paper introduces a model integrated with hydraulic actuator. completely novel unique method. In case that excitation random, average values displacement acceleration sprung mass are only 12.56 (mm) 3.78 (m/s2) if vehicle uses contrast, this value very large, up 30.70 6.53 passive used. Similarly, also large remaining survey situations. Overall, ??of significantly reduced when equipped an results research showed advantages method compared other methods.
