Influence of tyre pressure and vertical load on coefficient of rolling resistance and simulated cycling performance

摘要

The coefficient of rolling resistance (C_r) for pneumatic tyres is dependent on hysteresis loss from tyre deformation which is affected by the vertical force applied to the tyres (V_v) and the tyre inflation pressure (P_r). The purpose of this paper was to determine the relative influence of five different levels of P_r and four different levels of F_v on C_r and to examine the relationships of C_r with P_r and F_v during cycling locomotion. F_v was modified through carriage of additional mass by the subject.
