摘要: 通过建立导波传播的等效分析模型推导了二维点阵夹芯板中导波的频散方程, 并计算得到频散曲线. 建立了基于二维点阵真实结构的有限元模型, 并利用ABAQUS 软件模拟了导波在正六边形点阵夹芯板中的传播过程. 结果表明, 当频率较低时, 等效模型能够较好地描述导波沿整个夹芯板的传播过程.

Abstract: Based on an equivalent analysis model, the dispersion equations of guided waves in 2D lattice sandwich plate are derived, and the dispersion curves calculated. A finite element model is also built according to the real structure of 2D lattice. Propagation of guided waves in hexagonal lattice sandwich plate is simulated using ABAQUS software. It is demonstrated that the equivalent analysis model can well describe the guided waves propagating along the whole sandwich plate at low frequencies.

Key words: dispersion curve, guided wave, lattice sandwich plate
