摘　　要：格架条带是核燃料组件中的关键零件。为对冲制格架条带的级进模排样方案进行较客观的量化综合评价,针对格架条带的行业特点和应用环境,构建了考虑产品、模具、经济3个方面的多层次综合评价指标体系,并基于模糊综合理论建立了用于评价格架条带级进模排样方案的模型;通过对排样的有限元模拟分析,得到用于综合评价的原始数据,开展了对某试验型格架条带级进模排样的量化综合评价,最后通过物理冲制试验,验证了较优排样方案的可行性。结果表明:利用排样方案的有限元模拟分析结合模糊综合理论建立的综合评价模型,能够在格架条带的级进模排样设计阶段提供低成本且较为客观的有益指导,有助于更好地优化模具设计和提升产品的冲制质量与效益。The grid strip is a key part of components in nuclear fuel assembly.In order to conduct a more objective and quantitative comprehensive evaluation on the progressive die layout scheme for punching grid strip,a multi-level comprehensive evaluation index system was constructed considering the three aspects including product,die and economy according to the industry characteristics and application environment of the grid strip,and based on the fuzzy synthesis theory,a model for evaluating the progressive die layout scheme of the grid strip was established.Then,the original data for comprehensive evaluation was obtained by the finite element simulation analysis(FESA)of the layout,and the quantitative comprehensive evaluation was carried out on the progressive die layout of a certain experimental grid strip.Finally,the feasibility of the optimized layout scheme was verified through the physical punching test.The results show that the comprehensive evaluation model established by the combination of FESA of the layout scheme with the fuzzy synthesis theory can provide low-cost and objective helpful guidance in the layout design stage of the progressive die for the grid strip,and it is beneficial for the better optimization of die design and the improvement of punching quality and efficiency for product.
