液压系统多极模型的研究

Research on Multipole Module of Hydraulic Systems

依据电液相似系统原理,提出将实际液压系统的物理模型视为由若干个相互独立的子系统多极模型经若干节点拓扑而成的多极图。这种多极模型较通常使用的方块图更接近于真实的物理系统,比健合图使用方便,按照液压系统的工作原理图便可直接建成,可用来对液压系统进行更有效的计算机仿真和自动设计。介绍了液压系统多极建模的基本思想,给出了液压缸的多极模型。

Based on principle of similitude of electro--hydraulic, the hydraulic systems are regarded as thetopological multipole diagrams composed of certain inde-pendent subsystem multipole models by nodes. The mod-el is more similar to the actual physical system than pop-ular block diagram and more convenient for operationthan the bonding diagram. This model can be built onlyby schematic diagram of the hydraulic system. Themethod can be used more effectively in computer simula-tion and automated design for the hydraulic systems.
