車輪/レール接触における巨視滑り領域までの粘着力の挙動 : 静・動荷重条件における水潤滑状態での実験結果

抄録

In order to investigate the behavior of adhesion force from a microslip region to a gross sliding one, we carried out experimental studies mainly under water lubrication with static and dynamic contact loads. Every repeated experiment up to gross sliding showed a decrease in the adhesion coefficient under water lubrication and the traction force in the gross sliding region showed unstable behavior. Furthermore, it was recognized that the measured adhesion force during gross sliding agreed well with the values calculated with sliding acceleration and moment of inertia of rollers. The adhesion force under dynamic load was less than that under static load.
