The results of the research to substantiate the possibility and feasibility of raising the pneumatic spring suspension system for realization of efficient damping of vibrations of vehicle bodies, which are equipped with such a suspension, are presented. The influence of parameters of system components of the pneumatic spring suspension and gas-thermal and dynamic phenomena in it on the damping factor of vibrations and the development of the amplitudes of the vibrations in laminar and turbulent mode of the air flow through the orifice that connects the air spring and the additional reservoir was revealed. The dependence of the damping coefficient on the cross-section of the throttle orifice and the capacity of the additional reservoir in both modes of the air flow through the throttle was investigated. It was offered to take into account the "active" capacity of the air spring. It was also grounded the influence of natural frequency and density of the air on the damping ratio, which significantly improved the mathematical model that describes vibrations of boogie parts of vehicles on air springs. An example of calculations of the coefficient of damping of the pneumatic spring suspension for the vehicle was given. It is proved that the pneumatic spring suspension allows you to abandon hydraulic or other vibrations dampers completely by proper choosing of its parameters.
