摘要
介绍了利用功率键图理论绘制支架液压系统各元件的六法,通过必要的假设与简化,建立了支架液压系统的键图模型,为研究系统的动态特性,分析系统的工作过程及其影响奠定了理论基础,为进一步改进和完善支架液压系统的性能提供了重要的保证.
In shis paper,the method showing hydraulic system elements in a powered support with the theory of the power bond graph is introduced .The power bond graph model of the system is established in the paper by some necessary assumptions and simplications.It lays a theoretical basis on which studies the dynamic performance of the system and analyses its working process and influences.It also offers an important guarantee to improve and perfect the system performance further.
