Pneumatic suspension damping characterisation with equivalent damping ratio
International Journal of Heavy Vehicle Systems, 2012 The damping property of a pneumatic suspension with orifice-type fluidic resistance is characterized in this study. The nonlinear and linear models for the suspension system are first formulated and experimentally verified. The verified linear model is employed to derive a new pneumatic damping measure, equivalent damping ratio, based on which a ...
