【摘要】 键合图方法在多领域统一建模及仿真方面具有重要意义。为实现不同键合图仿真软件的键合图模型交换及重用,本文分析研究了基于XML(可扩展标记语言)的键合图模型交换及重用方法。文章首先分析了现有键合图仿真软件的特点,进而描述了W.Borutzky提出的键合图模型XML(可扩展标记语言)表达方法并在其基础上进行了如下改进:将模型及子模型的描述信息作为可选属性、精简模型的层次结构、去除冗余元素ports,最后阐述了不同键合图模型交换及重用方法。更多还原

【Abstract】 Bond graphs are especially suited for the modeling of multidisciplinary engineering systems. To support the exchange and reuse of models created in various softwares, an exchange format of bond graph models based on XML was described in this paper. The characteristics of different bond graph softwares were firstly analyzed. And the XML expression of bond graph models, proposed by W.Borutzky, was described. Then several improvements of W.Borutzky’s method were given in the next aspects: basic information about a model and its sub-model was treated as optional attributes, and hierarchical structure of a model was simplified, also redundant element "ports" was eliminated. Finally an approach to the exchange and reuse of bond graph models was discussed.更多还原
