Simulation and Experimental Study on Static and Dynamic Characteristics of Laterally Interconnected Air Suspension

Laterally interconnected air suspension can further improve air suspension performance. This paper presents the mathematical model of full vehicle and the test bench for laterally interconnected air suspension is established. Simulation and experimental results indicate that acceleration of sprung mass is reduced by laterally interconnecting the left and right air springs, and the larger pneumatic pipe diameter is, the better damping performance of the suspension will be. Compared with the conventional air suspension, laterally interconnected air suspension brings better ride comfort and driving stability for vehicles on uneven road.
