Comparison of Vibration Characteristics at the Freight Compartment of a Truck with and without Air Spring on the Rear Axle

This paper presented comparison of vibration characteristics of a 5-ton truck at the two kinds of rear axle suspension, a conventional leaf spring suspension and an air spring suspension. Vibration at the selected location in the freight compartment and the rear axle were measured while the vehicle was running on various kinds of road at the specified speed. At all kinds of the driving conditions used in the test the air spring suspension showed good performance of vibration attenuation, especailly at the frequency range of under 5 Hz.
