COMPARISON BETWEEN SUBJECTIVE AND OBJECTIVE RIDE COMFORT FOR MILITARY OFF-ROAD VEHICLES

摘要

The correlation between objective methods for determining ride comfort and subjective comments from crew in vehicles are investigated to determine the "best" ride comfort standard for use during suspension design and optimisation. An experiment is devised and executed in order to obtain both objective and subjective ride comfort values. The correlation between the different standards (ISO 2631, BS 6841, AAP and VDI 2057), measuring positions, measurement directions and calculation methods are determined. The emphasis is on the ride comfort of military vehicles operated under off-road conditions over typical terrains. A conclusion is reached as to which standards are best suited to specify and evaluate ride comfort.
