The aim of this work is to assess and compare the mathematical models of two pneumatic suspension architectures and show how they can converge, after appropriate simplifications, to a general linear form. In this work, a linear dimensionless model which holds for two types of air suspensions (FAV and BPR) has been developed. It has shown that the BPR suspension system has some clear advantages over FAV in term of design degrees of freedom. Moreover, its behaviour can be adjusted between a stiff or a soft one, simply by changing the air pressure inside a small volume, without using additional devices to change the resistance. Apart from this, the damping cylinder could be used simply coupled to a metallic spring, instead of an air spring, if there is no need to control the static height. This way, the nominal behaviour is the same as that of the air suspension shown but, changing the sprung mass the system, it is no more isofrequency, like a traditional system. Finally, even if there is yet any experimental validation, these kinds of models have been widely used and validated in the past decades.
