車椅子タイヤの転がり抵抗に関する研究

抄録

This reserch aims to construct a dynamic model of rolling resistance for wheelchair tires. The tire was modeled as an elastic body. It is considered that no slip originally occurs between the tire and the road surface. The relative displacement caused by the speed difference is thought to cause slippage. However,we thought that the circumferential spring of the tire worked so as not to cause slippage by shear deformation. I think that shear deformation occurs as rolling of the tire. Simulation of the rolling resistance force showed that the tendency to the vertical displacement of the tire was consistent. However,the calculated value of the rolling resistance force was 10 times larger than the measured value.
