| 摘 要： | 基于平面波动理论与电学系统方程的等价,建立管道气柱单元声学等效电路.采用MATLAB/SIMULINKL软件,通过谐振法对气柱系统进行电路仿真,得到其各阶固有频率,并与传递矩阵法计算结果相比较,误差很小,说明采用声电类比法计算气柱固有频率是有效的.

| Abstract: | Based on the equality in value of the plane wave theory equation and the electric propagation equation, the correspondence of the pipeline component with electric circuit elements was established. The natural frequencies of the gas column of the piping system were simulated with the software MATIAB/SIMULINK on the theory of electric resonance. Compared with the result of the transfer matrix method, the electro-acoustic method is proved to be valid. |
