摘　　要：为了研究充液管路管内声学传递特性,该文基于传递矩阵法、四端网络模型提出计算管内声学传递特性的声传递综合法,并提出了3种方法用于处理复杂管路部件与其他管路部件的连接,有效地将理论解析法和数值法或实验法获取的管路部件声学阻抗特征参数结合起来。使用理论解析法、数值法对单个管路部件的声阻抗参数、声传递响应进行了对比分析,二者计算结果吻合良好;对多直管部件的声传递特性分析结果表明:该文提出的管路部件连接处理方法1在计算管内声传递特性时能获得更好的计算精度;进一步分析直管-蝶阀-直管多管路部件串联管路系统声传递特性,计算结果与数值法吻合良好,验证了提出的声传递综合法在多部件充液管路系统声学特性分析时的正确性。In order to study the acoustic transfer characteristics inside a liquid filled pipeline,this paper proposes a comprehensive method for calculating the acoustic transfer characteristics inside the pipeline based on the transfer matrix method and the four terminal network model.Three methods were proposed to handle the connection between complex pipeline components and other pipeline components,effectively combining the acoustic impedance characteristic parameters of pipeline components obtained through theoretical analysis and numerical experiments or experimental methods.Theoretical analysis and numerical experimental methods were used to compare and analyze the acoustic impedance parameters and acoustic transmission response of individual pipeline components,and the calculation results of the two methods are in good agreement.The analysis of the sound transmission characteristics of multiple straight pipe components shows that the method 1 proposed in this paper is more accurate in calculating the sound transmission characteristics inside the pipe.On this basis,the sound transmission characteristics of a multi-component system composed of complex valve components were further analyzed,and the calculation results are in good agreement with the numerical method,verifying the correctness of the acoustic characteristics analysis of the multi-component liquid filled pipeline system in this paper.
