So far, there have been reports of experimental analysis of vehicle dynamic models and running resistance for wheelchairs, but theoretical analysis focusing on the tires themselves has not been made. Also, comparing wheelchair tires with automobile tires , the structure and shape are different, and the conditions such as operating speed are also different.
Therefore, in this study, I considered the model of tire deformation and the tire contact characteristics for wheelchair tires, and applied the theory of existing automobile engineering to predict the rolling resistance of wheelchair tires going straight on flat ground. I measured rolling resistance by experimental device and compared with the theoretical value.
