Influence of Damping Rates of Adaptive Hydropneumatic Suspensions on Vibration Loading of a Car

The improvement of effectiveness in solving problems of perfection of vibroprotective systems of modern autotransport aids is inseparably linked with the need of seeking new technical solutions that allow the wide use of different variants to control the liquid and damping characteristics of the suspension during the car motion. In this connection, the creation of mathematical models of cars with adaptive suspensions, which provide the debugging of suspension construction at the stage of computer simulation, is very promising. In this work, with the help of all-terrain car spatial model, the influence of damping rate of adaptive hydropneumatic suspensions on vibration loading of the car construction is estimated taking into account large displacements of solid bodies, exact kinematics of suspension elements and peculiarities of mounting them on the car.
