Outline
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.
