DESIGN ANALYSIS AND DYNAMIC BEHAVIOUR OF A PNEUMATIC SUSPENSION

抄録

In this paper we propose a method for the analytical study and the definition of schemes of vehicular passive suspensions that use pneumatic devices as springs and dampers. The article carefully describes the mathematical modeling and allows an evaluation of the effect of the different physical parameters on the performances of the suspension. The study has been done in the frequency domain and in the time domain, for a more complete evaluation of the performances. It is defined an optimal solution able to give an improving behaviour in comparison with the traditional solutions of suspension.
