시트동적강성분포측정방법 및 시트별특성분석

Abstract

Supporting stiffness of seats is an important component affecting dynamic characteristicscognized by a passenger. To analyze dynamic characteristic of a seat for vehicles operating onvarious road conditions, the seat vibration from road irregularity should be understood andcompared. In this study, the seat is analyzed as distributed supporting system. The dynamic stiffnessis measured using masses. The characteristic of the seats is analyzed by measuring distributeddynamic stiffness. The distributed dynamic stiffness of the seat is estimated on various locations andthe effects of each component such as spatial distribution, compression level and vibrationamplitude are analyzed. The influence of seat cover, elastic support and flexible polyurethane foamon the measured stiffness was analyzed.
