[0001] The present invention relates to the technical field of sheet metal parts, and more specifically, it mainly relates to a simulation analysis method for automotive instrument sheet metal forming based on ANSYS-Forming. Background Art

[0002] The forming analysis simulation technology simply means inputting the die and process conditions of the sheet metal into the analysis software, and simulating the entire deformation process through the software to judge the rationality of the die and process. Each simulation is equivalent to a trial die process. Therefore, the forming analysis software is relatively important in the forming design process of sheet metal parts.

[0003] The traditional simulation analysis method for automotive instrument sheet metal forming mainly relies on classical mechanics theory and numerical calculation methods.

The calculation efficiency is low, and the adaptability to new processes and new materials is also poor, resulting in a large deviation between the simulation results and the actual situation. Since the automotive instrument sheet metal forming is a complex problem involving multiple disciplinary fields and requires comprehensive consideration of factors such as materials science, computational mechanics, and manufacturing processes, the problem is difficult to solve.
