| 摘 要： | 用分布参数的方法对阀前管道系统进行动态分析,并用矩阵描述了控制阀前整个系统的传递关系.通过MATLAB分析与试验,结果表明:在控制阀前加蓄能器,不仅对流量脉动而且对液压冲击都有很好的吸收作用.

| Abstract: | The dynamic characters of the piping system before the control valve were analyzed with the distributing parameters methods and the transfer-relations of the whole system before the control-valve were described with matrix. Through the MATLAB analysis and test, the result shows that adding the accumulator before the control-valve is good at absorbing the flux pulsation and the hydraulic impact. |
