Abstract: Experimental results of the performance of a pneumatic suspension fitted in a single wheel station test rig are presented. Results for both a passive and slow-active version of the suspension are compared; the slow-active version involves an additional pneumatic actuator which has limited frequency response capabilities. The slow-active system is shown to provide worthwhile improvements in ride performance compared with the passive system. A theoretical model of the slow-active suspension is developed and predicted results are compared with experimental measurements on the rig. The mathematical model produces optimistic results for both passive and slow-active suspensions and the practical limitations of the experimental hardware are discussed.
