Air Suspension Performance Analysis using Nonlinear Geometrical Parameters Model 2007-01-4270

This paper studies the nonlinear characteristics of air suspension. The air spring's nonlinear model by the internal volume variation due to the compression of the spring and the variation of effective area pressure acts on is established. The comparison of simulation and experiment indicates the validity of the model in the paper. The characteristics of a quarter vehicle model with the air spring model presented in the paper have been studied. This analysis can guide the design of the air spring's shape and the piston contour, and understand the performances and the effects of air spring in vehicle.
