내구력 도로와 요철 도로에서 승용차의 승차감 지수 평가

This paper introduces the experimental results of ride values assessed for several passenger cars. The experiment was conducted at four vehicles on two roads for three persons by measuring the acceleration in the 12-axis of human. The results include the comparison of the ride values, such as the component ride values, overall ride value, and seat effective amplitude transmissibiity. It is proved that acceleration between 1 and 15Hz is the most significant in evaluating the ride quality. The contribution of the acceleration in each measurement axis is quantified from the component ride value. SEAT value shows a relatively low sensitivity for the road condition and human mass.
