As a core load-bearing component of the vehicle, the lightweight and reliability design of the air suspension integrated axle housing is crucial for improving overall vehicle performance. Addressing the limitations of traditional design methods in adapting to complex dynamic loads, this paper proposes a topology optimization method based on dynamic load spectra and the SIMP (Solid Isotropic Material with Penalization) method for non-uniform material distribution. A multi-condition topology optimization strategy applicable to diverse engineering scenarios is established. During the optimization process, the material density is adjusted iteratively based on analytical results to progressively refine the structure, ultimately achieving the optimal material distribution for the integrated axle housing. The study demonstrates that this method significantly reduces the axle housing mass by 90 kg while meeting strength and fatigue life requirements, providing an effective solution for lightweight design of air suspension integrated axle housings.

空悬一体化桥壳作为整车核心承载部件，其轻量化与可靠性设计对提升整车性能具有重要的意义。为解决传统设计方法难以适应复杂动态载荷的问题，提出了一种基于动态载荷谱与变密度法的非均匀材料分布拓扑优化方法，建立适用于广泛工程场景的多工况拓扑优化策略，在优化过程中根据分析结果调整材料密度，逐步实现结构的优化，得到一体化桥壳最优的材料分布。研究表明，该方法能显著降低桥壳质量，实现质量降低90 kg，同时满足强度与疲劳寿命要求，为空悬一体化桥壳的轻量化设计提供了有效解决方案。
