摘　　要：针对水下航行器及船舶管路系统中危害极大的水锤现象,本文采取环状气囊消声器装置对其进行控制。通过傅里叶变换得到频域信号验证装置性能,结合环状气囊消声器本身的声学验证实验数据,确定其应用上的适配性,并在时域计算中验证其对压力峰值的抑制效果。在计算中,对“纵倾平衡管路系统+消声器”的复杂管路系统模型采用1D-3D多维度模型耦合,避免受到计算资源的限制的同时,保证了模型构造尽可能接近实际情况,并对该方法的计算结果与传统瞬变流计算方法得到的结果进行比对,讨论其异同及原理。计算表明:环状气囊消声器确能对水锤波产生良好的抑制效果。Aiming at the extremely dangerous water hammer phenomenon in underwater vehicle and ship pipeline system,the annular airbag muffler device is used to control it.The performance of the frequency domain signal verification device is obtained by Fourier transform.Combined with the experimental data of acoustic verification of the annular airbag muffler itself,the adaptability of its application is determined,and the suppression effect on the pressure peak is verified in the time domain calculation.In the calculation of time domain,the complex piping system model of'pitch balanced piping system+muffler'adopts 1D-3D multi-dimensional model coupling to avoid excessive use of computing resources and ensure that the model construction restores the actual situation as much as possible.The results calculated by this method are compared with the results obtained by the traditional transient flow calculation method,and the similarities and differences and causes are discussed.The calculations show that the annular airbag muffler can produce a good suppression effect on the water hammer wave.
