Abstract：

A transient heat transfer finite element model (FEM) of die in soft zone of automobile B-pillar was established by software ABAQUS. Then, taking the die surface temperature as the optimization target and the uniform distribution of die surface temperature as the constraint condition, the finite element simulation calculating method based on the die surface temperature feedback control was established by Python secondary development tool, and the finite element calculations of die heating process under fuzzy control and fuzzy PID control were realized, respectively. The simulation results show that under the fuzzy control, the die surface temperature reaches (500±30) ℃ within fifty minutes, while under the fuzzy PID control with the enhanced constraint conditions, the die surface temperature reaches the process requirements after forty minutes, and the heating efficiency is significantly improved. Finally, through the die heating experiment controlled by the fuzzy PID simulation control program, the experiment result verifies the accuracy of the simulation, and the program design of the heating control of die is successfully guided.
