Abstract: This paper addresses automotive corrosion issues by proposing a cost controlled optimization method for automotive corrosion. Through in-depth analysis of automotive corrosion mechanisms and influencing factors, a dynamic corrosion cost calculation model is established. Combined with multi-objective optimization algorithms, a comprehensive optimization strategy integrating structural design, material selection, and anti-corrosion processes is presented. Research demonstrates that the proposed method significantly reduces automotive corrosion costs while enhancing vehicle service life and economic benefits. This study provides scientific cost-control solutions for corrosion protection to automotive manufacturers, offering critical implications for improving product quality and competitiveness.
