Assessing Ride Motion Discomfort Measurement Formulas

Abstract

After some context and motivation this article proposes gathering recordings of uncomfortable ride motions encountered in public passenger transport service and using a ride motion simulator to compare them. It explains how to adjust the amplitudes of the sample recordings so that they all cause equal discomfort. Then, if a formula is proposed for estimating the discomfort a vehicle ride motion would cause, it can be applied to each of the equal discomfort recordings, and the dispersion of the resulting discomfort scores will indicate the realism of that formula; the lower the dispersion, the more realistic the formula.
