The low-frequency vibration of a passenger car determines the “hardness” and “harshness” in the ride comfort quality of a luxury passenger car. Many studies on the objective evaluation of ride quality have been performed, and diverse methods for such evaluation have been proposed. The vibration metrics that have been mainly used in the industrial field are the power spectrum density(PSD) and the vibration dose values(VDV). PSD has been used for evaluating the stationary ride comfort quality in the frequency domain, and VDV has been used for evaluating the transient ride comfort quality. These vibration metrics, however, cannot determine which condition is stationary and which is transient. This paper thus proposes a new vibration metric that can distinguish the stationary condition from the transient condition, and presents the developed novel ride comfort index for the objective assessment of ride comfort quality based on the new vibration metric. |
