Abstract |
|
With the wide application of functionally graded carbon nanotube reinforced composite (FG-CNTRC) structure in engineering, vibration and noise are inevitable in the complex working environment. This paper investigated the acoustic response and wave propagation characteristics of FG-CNTRC plates. Based on the third-order shear deformation theory, the dynamic equation of FG-CNTRC plate was derived using Hamilton’s principle. The acoustic response characteristics of FG-CNTRC plate under the concentrated harmonic excitation were solved and verified. By using the displacement function of wave propagation in an infinite plate, the dispersion characteristic equation of FG-CNTRC plate was obtained, and its dispersion curve, phase velocity and group velocity were solved. Then, the effects of parameter changes on the acoustic response and wave propagation in the FG-CNTRC plate were analyzed and discussed. This research provides a theoretical reference for the optimization design of FG-CNTRC structures. |
