典型系统基于架构的层级化建模技术研究

随着工业化与信息化的深度融合,计算机建模与仿真技术已广泛应用于系统或产品的研发过程中,但其存在模型混乱、碎片化、层次不清晰、复用性差的问题。基于对系统架构的理解,提出了一种基于系统架构开展系统层级化建模的方法。在建立模型时将整个系统分解为系统层、子系统层和部件层的多层次模型；各层级模型的接口均与系统架构定义的接口关系保持一致,实现设计的连续性,为基于模型的设计提供有效的支撑。该方法能清晰表述模型的目的、层级和颗粒度。文中以典型伺服作动系统为例进行了验证,结果证明了方法的有效性。

Research on Hierarchical Modeling Technology of Typical System Based on Architecture

With the deep integration of industry technology and information technology,computer modeling and simulation has been widely used in the development process of systems or products.However,the models have some problems such as disordered,fragmented,unclear in hierarchy,poor in reusability and so on.A method based on system architecture was proposed to develop system hierarchical models .When building the models,the whole system can be divided into multi-level with system level,subsystem level and component level.The interface of each hierarchical model is consistent with the interface defined by the system architecture.It can achieve the continuity of the design and provide effective support for the model-based design.The method can clearly describe the purpose,level and granularity of the model.The typical servo actuation system was used as an example to verify the effectiveness of the method.
