摘　　要：为了弥补复杂装备CAE软件缺乏开放式、可组合式系统架构的短板,提出了一种基于多模块分层组合模型的全链路CAE软件耦合方法。首先,基于离散事件系统规范(DEVS)中离散事件模型+有限状态机+连续时间模型的组合模式,构建CAE软件前处理、数值求解、后处理阶段的核心构件库。其次,采用多模块分层分级的组合模型,基于多智能体系统的事件触发驱动机制,实现全链路CAE核心软构件的自动化耦合。面向盾构/高铁应用场景的仿真结果表明,将CAE全生命周期链路进行构件化细分、自动化耦合,利于研究多因素耦合作用下的复杂装备产品设计。此外,多模块组合模型的架构支持CAE软件核心模块的灵活组合与独立部署,实现对CAE软件向云服务平台整合的支持。To make up for the lack of open and composable system architecture of CAE software for complex e⁃quipment,an automated coupling method for CAE software based on a multi-module hierarchical combination model is proposed.Firstly,based on the combination mode of the discrete event model,finite state machine and continuous time model in the discrete event system specification(DEVS),the core component library for preprocessing,numerical solution and post-processing stages of CAE software was constructed.Secondly,the hierarchical combined model of multi-module was adopted,and the automatic coupling of the core soft components of the full-link CAE was realized based on the event trigger drive mechanism of the multi-agent system.The simulation results in the shield/highspeed rail application scenario show that the componentization and automated coupling of the CAE whole life cycle link is conducive to the study of complex equipment product design under the multi-factor coupling scenario.In addi⁃tion,the architecture of the multi-module combination model supports the flexible combination and independent de⁃ployment of the core modules of CAE software,and realizes the support for the integration of CAE software into the cloud service platform.
