Analysis of a truck suspension database

International Journal of Heavy Vehicle Systems (IJHVS), Vol. 9, No. 4, 2002

Abstract: Experimental data from 61 heavy vehicle suspensions are analysed in this paper to investigate the trends in performance of contemporary suspension designs. Two suspension databases and a mathematical vehicle model are used to calculate the ride and roll performance of heavy vehicles, based on the measured suspension parameters. The suspensions are divided into eight categories according to their spring and axle types. The contribution of suspension springs to rollover stability is evaluated, and the conflict between vehicle ride and roll stability is analysed. Methods for resolving this conflict are discussed from the viewpoint of systematic design principles. A comparison of measured total roll stiffness and roll centre height with rollover threshold is conducted to search for the possible patterns of performance.
