Analysis rolling resistance of wheel chair.

Abstract

Recently, many studies of rolling resistance of wheelchair tire are being for that rolling resistance of the tire is connected with the burden on wheelchair user. Internal damping of the rubber with the tire deformation account for nearly all dissipation energy during the rotation. Considering the elasticity of the tire, deformation of the tire grounded rugged road surface with a projection differ from that grounded flat road surface so rolling resistance increase depending on road surface profile. Therefore we constructed the mechanical elastic deformation model for calculation of running characteristics and dissipation energy during rolling road surface with a projection. The relation between projection height and dissipation energy can be derived, but the model invalid for quantitative analysis so need to be improved.
