Evaluation of Ride Comfort by Differences in Tire Pressures of Manual Attendant Controlled Wheelchairs

Abstract

One of the indicators that affects the comfort of a wheelchair is tire pressure. However, since the English valve which is most frequently used for a wheelchair has a structure that it can not put out air even if it can be arbitrarily inserted, how much the tire pressure of the wheelchair will affect the vibration Has not been revealed yet. The purpose of this study was to measure the vibration generated in the wheelchair due to the difference in tire pressure using the pneumatic pressure indicator dedicated to the English valve and the influence of the road surface and vibration of the manual attendant-controlled wheelchairs.
