摘要
为了解决液压系统的减振与降噪的问题,本文提出一种多相式流体滤波的方法。多相式流体滤波器是液相、气相与固相滤波器的不同组合,由它们分别对不同频段内的压力脉动与噪声进行滤波。多相式流体滤波兼具了组成它的各相滤波单元的优点,它具有滤波衰减率高、响应频带宽广以及体积小等一系列优点。本文将论述有关多相式流体滤波的工作原理及其数学模型,并介绍有关的实验结果。
In order to work out a solution for decreasing the vibration and noise in the hydraulic systems, the way to filter hydraulic wave by multiphase wave filtering is presented in this paper. Multiphase hydraulic wave filter is a sequential combination of the liquidphase,gas—phase and solid—phase wave filter which separately filter the vibration wave and noise over a frequency range.It puts together the advantages of the various filters and has the character of the high filter attenuation coefficient,the wide bandwidth of frequency response and small volume,this paper presents operating principle,the mathematical models,and experimental results.
