Rubber has strong nonlinear viscoelastic characteristic. Under effect of the periodically changing external force,it will show the phenomenon of lagging deformation and mechanical loss,which means deformation lags behind stress changes and the situation of loss of work is caused by the hysteresis. Loss of work will be transformed into thermal energy and makes the temperature of rubber and the object in contact with it rise,which will thereby affect the dynamic characteristics of the structure. Based on a pair of mutual rotating and squeezing steel-rubber rollers as the research object,the finite element simulation software Ansys is used in this paper to analyze the temperature field of the structure. As a result,temperature distribution characteristics of two directions are obtained. One is squeezing area along the direction of the wall,the other is along the direction of thickness of rubber. Then the influence of the rotating speed and the pressure between two rollers on temperature of rubber is analyzed. The temperature experiment of mutual squeezing contact steelrubber roller is carried out on the experimental platform via using infrared thermal imager and infrared thermometer. The experiment data are in accordance with the simulation results on regulation of temperature distribution as well as high degree of similarity on value,which shows the effectiveness of simulation. Research results are of great significance for temperature characteristic analysis of rubber structure.
