| Abstract: |
| In this study，polyurethane wear experiment under dropping lubrication was carried out by block-on-ring wear test.The wear conditions such as different pressure，rotating speed and wear time were investigated and the wear depth was measured by profilometer.The contact force of the grinding surface under different pressures was calculated by finite element analysis software Ansys.The empirical wear formula of polyurethane specimen was obtained through nonlinear regression fitting of test data based on Rhee’s wear model，which was in good agreement with the experimental measurement. |
