| 摘 要： | 泵输出的周期性脉动流体的压力脉动，是引起流体谐振、激励管路振动和噪声的主要原因．为了减少振动造成的故障，人们从两方面进行研究：一是研究开发高性能滤波器，消除和抑制脉动压力幅值；二是合理设计管路结构参数，避免流体谐振．两者均需计算不同结构参数和频率下的脉动压力，了解其幅频特性。本文采用刚度矩阵法，对管路各子系统耦合，求解管路系统压力分布，并进行了仿真与实验验证

A METHOD OF CALCULATING PRESSURE DISTRIBUTION OF PERIODIC PULSATION FLUID TRANSPORTED IN PIPING NETWORK |
| |
| Abstract: | The pressure pulsation induced by the pumped periodic pulsation fluid is the main factor of causing fluid resonance and stimulating pipelines vibrations and noise. In order to reduce the faults caused by the vibrations of pipelines, two aspects have been researched: one is to develop high quality filters, weaken and restrain the crest of pulsation pressure; the other is to design structural parameters of the piping network and eliminate the fluid resonance. Both need calculating the pressure pulsations of different structural parameters and frequencies, and knowing the amplitude frequency. In this paper the stiffness matrix technique is used for treating the coupling of subsystems of pipelines and calculating the pressure distribution of the piping network and it is tested by simulation and experiments. |
