| 摘 要： | 基于协同优化方法,建立了面向成本的飞机结构优化设计模型.该模型不同于传统的结构设计中以质量最小或结构效率最大为优化目标,而是以寿命周期成本为目标,通过相同的结构尺寸变量将结构质量与制造成本联系起来.其中以重量表征油耗成本,寿命周期成本模型被简化为制造成本和油耗成本的函数.在iSIGHT优化平台实现了这一结构协同优化的过...

| Abstract: | The model of aircraft structure design for cost was established based on Collaborative Optimization.The model took LCC of aircraft as the objective of optimization,rather than minimum weight or maximum structral efficiency in traditional design,linking manufacturing costs models with structural analysis models through shared design parameters.LCC model was simplified to the function of manufacturing cost and fuel brun reflecting weight penalty.The optimization was implemented with iSIGHT.The analysis and co... |
