| Abstract: | The physical and mathematical models for calculating the non-stationary temperature fields of steel disc in wet multidiscs brake are established and the differential equations are derived in this paper. The Crank-Nicolson differential method and Gauss-Seidel iteration method are used to calculate the temperature distribution of steel disc in the radial and axle directions and the effect of thickness of steel disc on temperature is also analyzed,which is the basis of calculating the stress fields and thermal deformation. |
