| 摘 要： | 本文分析研究了液压系统中液流在连接不同直径管道的装置处，流动参数发生瞬变的物理特征。理论分析和实验研究表明，使用特征线法计算管道系统时，在大小管连接截面处，应考虑到该处的动量变化，才能准确描述液压管道系统的瞬变过程。

| Abstract: | This paper deals with the physical characteristics of the transient of flow parameters in hydraulic system when fluid flows through pipe junction with different diameter. The theoretical analyses and experimental results show that when characteristics method is used to calculate system of pipes with different diameters and the changes in momentum is taken into consideration,transient procedure in the system of hydraulic pipe can be described accurately. |
