N2 - Superplastic forming equipment completes the forming process making use of the excellent ductility of some metal (Ti2AlNb) in the ultra-high temperature, in which the temperature control is extremely important. A thermal resistance network model is established in Modelica in order to control the temperature uniformity and stability, and a simulation model of numerical analysis is established in ANSYS according to the actual engineering parameters. The temperature distribution of the two models is consistent under the same boundary condition, which verified the rationality and accuracy of the Modelica model. The temperature field of the superplastic forming equipment performs stably through the PID controller based on the Modelica model. After the temperature of the thermal resistance network model is analyzed, the reasonable temperature control instruction is generated by decoupling, which makes the internal temperature distribution of the forming equipment uniform.
