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.

为提高某车型全铝车架的碰撞性能与轻量化水平，基于多学科性能目标，采用功能导向与材料匹配的设计策略，分区域开发实现性能与轻量化之间的平衡。结构设计阶段采用基于变密度法的拓扑优化方式，覆盖吸能件和铸件关键区域，解决性能冲突及最优架构设计难题。轻量化设计阶段采用基于参数化模型的料厚优化方法，实现各区域材料厚度的最优分布。在满足强度、耐久性、噪声、振动与声振粗糙度（NVH）性能及碰撞安全性能要求的前提下，全铝车架质量减轻16.7%，质量占整车质量比例为7.5%，经系列试验验证，各项性能均满足开发目标要求。
