Abstract:

Aimming to build the association among different levels of design information and simulation information of different physical domains of the complex mechatronic products, a SysML-based framework of an integration of hierarchical design and simulation information was proposed for supporting the model-driven design of multi-domain complex mechatronic systems. An integration information model was established based on the extension mechanism of stereotype of SysML. After that, the meta-models of SysML and Simscape, a typical simulation modeling language, were explored and the mapping rules between them were also studied. The integration method between the system-level design and simulation information was proposed based on triangular graph grammar(TGG). At last, some examples were shown to illustrate the proposed method and some discussion was also given.

Key words: model-driven, complex product, SysML, system design, integration of design and simulation

摘要：

针对如何为复杂机电产品建立不同层次、不同物理域的设计信息及其与仿真信息间的关联这一重要问题，以系统建模语言SysML为基础，提出了支持模型驱动多域复杂产品多层次设计与仿真信息集成框架;建立了基于SysML扩展的核心集成信息模型，以支持系统设计与仿真集成及不同层次设计过程的信息集成。以此为基础，重点研究了SysML和Simscape建模语言的元模型及其间的映射规则，以及基于三元图文法的系统层设计信息与仿真信息动态关联与集成的方法。最后给出了实例进行分析验证。
