Modeling and Stiffness Characteristic Analysis of the Semi-Active Interconnected Air Suspension

Abstract:

Based on structure and working principle of semi-active interconnected air suspension, whole vehicle dynamic model including interconnected air springs system model, damper model, vehicle body and tire model is established. The changes of parameters such as connect pipe diameter, unilateral or bilateral excitation input phase difference that have effect on the air spring stiffness characteristic are simulated when air springs in the interconnected condition. The simulation results show that, interconnection of air springs can reduce the stiffness of air spring, and vehicle ride performance and riding comfortable performance can also be improved effectively.
