As requirements for combat capability in modern ship increase greatly, and shipborne electric and electronic facilities configurations become more and more complex, ship design focus more on stealthiness, integration and electromagnetic compatibility(EMC). The demonstration and design of EMC should be more accurate and intelligent, by using digital assistant design methods. So we proposed a ship EMC digital design method, introduced the concept and procedure of EMC top-level quantitative pre-design. And we analyzed functional requirements of ship EMC digital design assistant platform, and provided some EMC design and pre-validation ways. Then we designed an assistant design system named Modern Ship EMC Top-Down Quantitative Design Platform. This platform is based on digital simulation softwares and provides a unified framework for ship designers to solve the problems in ship EMC design, such as qualification of criteria, scheme optimization as well as quantitative evaluation, etc.%随着对现代舰船作战能力需求的大幅提高,舰载电力电子设备配置方案日趋复杂,舰船隐身性、集成性与电磁兼容性(EMC)成为论证和设计的焦点,EMC论证和设计迫切需要向数字化、精确化和智能化方向发展.提出了舰船EMC数字化设计方法,定义并阐述了EMC顶层量化预设计概念和内涵,提出了设备EMC指标设计和预检验方法以及EMC设计流程,并对进行EMC辅助设计的数字化平台功能需求进行了分析.在此基础上,提出了“舰船EMC辅助量化设计平台”框架.该设计平台基于数字化预测的仿真系统,能在一个统一的平台上帮助论证和设计人员解决舰船EMC论证和设计中指标量化、方案优选和定量评价难题,将成为舰船实现EMC数字化论证和设计不可或缺的手段.
