Abstract: To address the issues of structural redundancy, stress concentration, and uneven thermal deformation in key components of steel rolling dies under high-load conditions, a coordinated topology optimization-based structural design method for the upper die and slider is proposed. Based on the conventional topology optimization framework, multiple constraints, including volume fraction, stress, deformation, and material distribution, are incorporated. Meanwhile, both impact loading and uniform static loading conditions are considered to establish a unified multi-condition optimization model, enabling the coordinated improvement of structural lightweight design and mechanical performance. Finite element simulations are conducted to compare the structural performance before and after optimization in terms of specific energy absorption, maximum equivalent stress, natural frequency, energy dissipation rate, and deformation uniformity. The results show that the optimized structure achieves up to a 19.6% increase in specific energy absorption and a 29.4% reduction in maximum equivalent stress, while the average natural frequency and energy dissipation rate are improved by 13.2% and 26.3%, respectively. Thermal analysis further indicates that the temperature rise is effectively controlled under different loading conditions, demonstrating good thermal stability. The results confirm that the proposed method can achieve coordinated optimization and performance enhancement of key components under multi-condition constraints, providing practical guidance for the engineering design and optimization of steel rolling dies.
