多领域虚拟样机混合建模方法

Hybrid-modeling Approach to Multi-disciplinary Virtual Prototyping

为实现支持虚拟样机 (VirtualPrototyping ,VP)全生命周期决策评估的多粒度的、可执行的系统抽象仿真模型 ,借助软件IC和O -O思想提出了经济易行的、支持多领域并行协同工作的混合建模方法。VP上游概念设计采用自上而下的图论设计方法 ,将多领域部件按需求集成为可重构的子系统 ,而封装在部件内部的下游详细设计则充分发挥现有商业化CAX软件工具的优势自下而上的展开 ,整个系统的综合设计采用UML ,以保证整体的可回溯性和上下游设计的无缝集成。

To support virtual prototyping (VP) system lifecycle wide design validation,evaluation and decision using multi graininess executive design abstractions,an economical collaborative multi disciplinary hybrid modeling approach is proposed on the basis of soft IC and object oriented.On the one hand,graph theory used in up stream design integrated multi disciplinary components into subsystems top down so that their reconfiguration can satisfy various requirements.On the other hand,cost effectively CAX tools adopted in down stream design carried out encapsulated components' internal detail design bottom up.Meanwhile,the whole VP system modeled with UML ensured the iterated seamless design integration of both up stream and down stream design.Finally,a feasible modeling example of mechatronic control VP system is given by using this hybrid approach.
