基于DFx的T/R组件模块布局仿真系统研究

针对传统的T/R组件模块布局方法效率低,花费大的问题,运用并行工程(Concurrent engineering,CE)的思想,基于DFx设计了T/R组件模块布局仿真系统,并对实现系统的各项关键技术进行了研究。该系统建立了T/R组件元件库,通过调用元件库快速建立T/R组件模型,并基于此同一模型的初始布局进行热分析、电磁兼容分析和装配干涉分析,再根据分析反馈进行热、电磁和装配工艺的协同设计,得到优化的T/R组件模块虚拟布局方案和装配工艺。该系统应用于某型雷达T/R组件的设计,取得良好效果。最后指出了此系统进一步完善的方向,即建立专家系统进行分析结果的智能反馈,并根据反馈结果引入遗传算法实现T/R组件模块布局的自动优化。
