本文用传递矩阵法建立了蓄能器的声学模型,推导了蓄能器插入损失计算公式,分析 了蓄能器对管路中流体脉动衰减的作用,并进行了试验验证。%The process of pressure ripple with an accumulator in piping systems is discussed,the acoustic model is obtained to deduce the transfer matrix and the equations of insertion loss. The accumulators character of pulsation attenuation is obtained.Some experiments are done to verify the theoretical attenuation of pressure ripple when the accumulator is equipped.
