摘要
探讨了复杂多能域耦合系统相似的基本要求,以适用于多能域系统建模的键合图为工具,给出了键合图的相似分析,在此基础上,从系统论的角度出发,利用层次分解法论述了系统在各层次上功能相似及结构相似的概念,并推导出了两类相似对应的相似条件,从而提出了一种能适用于指导复杂多能域耦合系统相似研究的相似理论与方法,并将其应用于一个典型复杂多能域耦合系统——高速轧机的相似分析。
The basic requirements for the similarity of these systems were advanced. The similarity analysis of bond graph was presented. The concepts of functional similarity and structural similarity for each hierarchy of the system were explored and the similarity requirements for the two different similarity categories of each hierarchy were derived by utilization of analysis of hierarchy based on the perspective of system theory. Thus, the similitude theory and method which can be applied to instruct the similarity research on complex system with multi--energy domains was established. Finally, the new method proposed herein was utilized in the similarity analysis of a temper mill system which is a typical complex system with multi-energy domains.
