Glebov A.O., Karpov S.V., Karpushkin S.V.  Comparing the techniques of temperature field modeling for hot induction plates

The paper examines 2 techniques of temperature field modeling for hot surfaces of heating plates of rubber goods presses; the first one uses ANSYS, while the second one is based on finite integral transform method implemented in MathCad. The effectiveness of both techniques was evaluated by comparing the results with experiment data and subject to the modeling time. The recommendations are made on using the techniques in the design of heating plates for industrial presses.
