| Abstract: | Contact temperature is one important working proprieties of friction pairs,there are no study on the contact temperature fields of rough surface contact at present.The methods of calculating the contact temperature fields are presented.On the basis of taking rough surface and debris effects into account,the temperature fields of sliding friction pairs are calculated.And the effect of temperature on the sliding friction pairs scuffing proprieties is discussed.The result shows that there are obvious enbance of the contact temperature comparing the smooth surface contact to the rough surface contact.If the coefficient of rough influence equal 0.1 and 0.5,the contact temperature will enhance by 14% and 103%.The contact temperature will enhance once again if the debris embed in the surface.If the material of the friction pairs is 45 # steel,Supposing the surface film has been destroyed,the temperature of debris embed point will come to the material welding temperature. |
