Numerical simulation and optimization of deformation heating process of automobile forging is an effective method, which can be used to improve forging process and product quality. The following are the general steps and methods for numerical simulation and optimization of the deformation heating process: Preliminary preparation: First of all, it is necessary to collect relevant material property data, heating equipment parameters and forging process parameters. At the same time, it is necessary to model the geometry of the forging and determine the mesh division of the model. Material modeling: The mechanical properties data of forged materials are transformed into a material constitutive model that can be used for numerical simulation, usually using elastoplastic or thermoplastic constitutive models. Numerical simulation: The heating process is numerically simulated by finite element software. According to the actual situation, two-dimensional axisymmetric model or three-dimensional model can be used. Verification of simulation results: The results of numerical simulation are compared with experimental data to ensure the accuracy and reliability of simulation results. Optimization design: Optimize the deformation heating process by adjusting the parameters of heating equipment and forging process parameters. Genetic algorithm, simulated annealing algorithm and other optimization methods can be used to find the best combination of process parameters. Analysis of simulation results: The optimized deformation heating process was simulated, the influence of various parameters on forging deformation and temperature field was analyzed, and the optimization effect was evaluated. Results Application: The optimized parameters of the deformation heating process were applied to the actual production, and the production test was carried out. According to the actual production situation, continuous optimization and improvement. Through numerical simulation and optimization, the quality and efficiency of deformation heating process of automobile forgings can be effectively improved, material waste and production cost can be reduced, product quality and process stability can be improved.
