本文的目的是有助于理解气动系统中支管的非定常流动。支管用于各个工业领域的气动管道系统。为了预测气动管道系统的非稳态压力变化，除了单管的动态特性外，还需要掌握支管的动态特性。然而，尽管针对单管动力学的研究积累了如此多的研究，但很少有研究报道由于振荡流引起的支管压力变化。本文报道了给定振荡流下气动支管压力变化动态特性的实验研究。本文还提出了一种模拟方法来预测振荡流下气动支管中的压力变化。与实验结果进行比较，验证了对于高达 5 Hz 的振荡流模拟的有效性。
The purpose of this paper is to contribute to the understanding of unsteady flow of branch pipes in pneumatic systems. Branch pipes are used in pneumatic pipe systems in various industrial fields. To predict the unsteady pressure changes in the pneumatic piping systems, it is necessary that the dynamic characteristics of branch pipes are at hand, in addition to the dynamic characteristic of single pipe. However, while so many studies are accumulated for a single pipe dynamics, few studies have reported the pressure changes in branch pipes due to oscillatory flow. This paper reports an experimental study on the dynamic characteristics of the pressure change in a pneumatic branch pipe under given oscillatory flow. The paper also proposes a simulation method to predict the pressure changes in a pneumatic branch pipe under oscillatory flow. The validity of simulation is verified for oscillatory flows up to 5 Hz, comparing with the experimental results.
