【Abstract】 The reliable transmission of detonation from micro-charges remains a critical challenge in fuze miniaturization.To address this issue, a closed assembly dimension chain model with an initiation layer, multiple support layers and a pedestal layer is developed based on the multi-layer assembly architecture of micro-charges in the explosive train.The model is constrained by both dimensional tolerance and manufacturing cost.An adaptive elite-guided hybrid genetic algorithm（AEGH-GA） with a feedback control loop is proposed, which incorporates the booster hole gradient increment criterion, dimensional tolerance-machining accuracy constraints, cost-tolerance constraints, and evaluation criteria for dimensional chain tolerance design.Through parameter optimization, the algorithm enables 1.22 mg Pb（N₃）₂（design dimensions: ??1.7×1 mm） to reliably initiate and complete detonation of a 21.5 mg HNS-IV charge（design dimensions: ??2.4×3 mm） and make it undergo a complete detonationit undergo a complete detonation.The resulting optimal tolerance design for the assembly dimension chain ensures a booster hole penetration rate exceeding 99.999% with a cost lower than 56.5,thereby establishing a robust foundation for enhancing the reliability of energy transmission in micro-charge systems.更多还原
