Abstract:Thermal resource analysis and thermal transfer mechanism analysis of highspeed precision press are carried out in detail basing on thermal properties; completed the computation of initial condition and boundary condition of thermal analysis; modeling for the whole machine finite element model is done in Solidworks; thermalstructure coupling analysis of whole machine is done in ANSYS; then temperature field and stress field of whole machine in steady state environment are built, processing errors are computed. Finally, compared with actual press temperatures measured by infrared thermal imager, the reliability of temperature field simulation analysis is validated, which provides theoretical basis for the structure design and the thermal balance design of the press.
