The era of future mobility is emerging, and ride comfort will be a telling factor as customer demand increases. Ride comfort performance should be rapidly developed in future mobility systems, so predicting ride comfort by using only the suspension system of the vehicle would be very helpful. In this paper, test rigs for ride comfort testing(suspension module test rig, dynamic comfort roadway, and roller bench) were used to determine the effect of the vibration characteristics of suspension systems on ride comfort performance. Tests on vibration characteristics and ride comfort were carried out by using only the suspension test rig, and the correlation between performance and vibration characteristics was analyzed. Ride comfort development at the system level, based on the analysis of suspension vibration characteristics, was proposed. Likewise, the vibration characteristics target for the suspension system, which can help improve ride comfort and design component specifications, was suggested. |
