Urban Bus Driver Ride and Road-friendliness. Part II: Subjective Suspension Damping Tuning and Objective Optimisation

This article describes how three-dimensional ride dynamic model of an urban bus, which was developed in first part of the study, is applied to determine desirable suspension damping through subjective tuning and objective parametric optimization under a wide range of operating conditions, including vehicle speed, load, road roughness and tire inflation pressure. While the subjective method relies on the motion perception of the experimenter, the objective approach is limited to performance measures considered in the optimization problem. The results presented in the article suggest that both the objective and subjective methods could yield enhanced driver ride and dynamic tire loads over the most probable ranges of operating conditions when compared with the baseline dampers. The ride responses of the candidate bus that was equipped with subjectively tuned dampers were subsequently measured, which further demonstrated applicability of the model for suspension damping tuning for enhancing both the driver- and road-friendliness.
