Collaborative Optimization of Lightweight Mechanical Structures in the Design of Automobile Body Crash Resistance

Zhu Weiya,Yang Yuhao (Shangqiu Institute of Technology,Shangqiu 476OOO, China)

【Abstract】To resolve the inherent contradiction between lightweighting of automobile bodies and crash resistance, thispaperadopts "multi-objectivehierarchicaloptimization"and"machineleaming-asistedagentmodeling"technologies, innovativelyconstructing a full-process integrated collaborative optimization framework covering material selection, structuraldesignndprocsingtechnology.Fistly,itelaboratesonthetheoreticalbasisandmethodsstemoflgtweight mechanicalstructuresinthedesignofautomobilebodycrashresistance.Secondly,itanalyzesthekeytechnicalsystem and implementation pathofcollaborativeoptimization.Finally,it discusses the innovative methods and technological breakthroughs in this field, providing references for related research and engineering applications.
