The thermal boundary conditions of the high speed press were determined by calculating the heat generate resources and coefficient of heat transfer based on obtaining kinetic and dynamic parameters of the press.The finite element method was used to develop the thermal model of the press,and the changes of temperature distribution were studied.The results of the calculation and experiment show that the thermal FEM model can simulate properly the temperature distribution of the press during its operation.It provides the numerical analysis and experimental research basis for the press thermal error analysis design and experiment research.
