摘要
本文在液压元件四极子传递矩阵的基础上,研究了液压管道系统的时域动特性,将数字信号分析程序FFT应用到液压管道系统的瞬态仿真,并开发了相应的仿真程序TSHS。用该程序对几个典型液压管道系统进行瞬态仿真,证明了该方法的正确性与实用性。与其它方法相比,本文的方法更简单、方便。
In this paper, based on the four-pole transfer matrix models of hydrauliccomponents, the dynamic characteristics of hydraulic pipe-systems areinvestigated in time domain. The digital signal analysis program FFT isapplied to the transient simulation of hydraulic pipe-systems, and the programpackage TSHS is developed. With this program, the transient response ofseveral typical pipe-systems is simulated. It's proved that the methodpresented in this paper is accurate and practical. Compared with othermethods, this one is more simple and convenient.
