摘要
研究了声学有限元的单元方程和总体方程,在其商用软件平台上完成了消声器传递特性的数值仿真计算,所得结果与实验测量结果的幅值与相位基本一致.
The element equation and the total equation of the acoustical FEM are studied, the transmission property of the silencer is calculated on the commercial software platform, the numerical results of the amplitude and the phase are consistent with those from the experimental measurement.
