摘要
通过研究液压系统中油液在管道流动时,工作参数发生瞬变的物理特征,指出使用特征线法分析和计算液压管道系统时,在连接不同直径管道连接处,应考虑该处的动量变化。
This paper, based on the resarch on the physical characteriscs that the tranaient of the flow parameters occurs when the fluid flows in the pipeline of the hydraulic system, brings forward the point of view that the change of momentum at the joint of pipeline of different diameters should be counted when analyzing and calculating the hydraulic system by the method of characteristic line, therefore the transient process would be described precisely.
