Abstract

In Volgograd State Technical University, on the basis of chassis dynamo, an experimental modular unit was created for testing the load on air suspension in various regimes and with various combinations of amortization nodes: hydraulic shock absorber, air damper, inertial friction damper, and dynamic absorber. The unit allows determining the characteristics of elements and vibration isolation qualities of suspension as a part of a single-support oscillating system in view of imitation of sprung and unsprung weights of a car per one wheel. The program of tests envisages determining the characteristics of tested elements separately and vibration isolation qualities of air suspension with different combinations of damping units during setting, the power and kinematic influences on suspension in a wide range of frequencies that appear during car’s movement. As a result of the tests, optimal parameters of combined amortization of the studied air suspension are determined which ensures a high level of vibration isolation of the car in the whole exploitation range of frequencies.
