Outline
To enhance both the crashworthiness and lightweight design of an all-aluminium frame, a multidisciplinary, performance-oriented development strategy was formulated. The methodology integrates functional zoning with material matching, enabling a region-specific development process that achieves an optimal trade-off between structural performance and mass efficiency. During the structural design phase, a topology optimisation approach based on the variable density method is implemented, with particular attention paid to energy-absorbing components and critical cast regions. This facilitated the resolution of conflicting performance requirements and the establishment of an optimal structural architecture. In the subsequent lightweight design phase, a parametric thickness optimisation technique is adopted to determine the most favourable distribution of material gauge across all functional zones. Under the precondition of satisfying requirements for strength, durability, Noise, Vibration and Harshness(NVH), as well as crash safety, the mass of the all-aluminium frame was reduced by 16.7%, corresponding to 7.5% of the total vehicle mass. The final design was subsequently validated through a comprehensive series of physical tests, and all performance indicators were confirmed to meet the predefined development targets.
