- Abstract
Exploring the vibration transmission law in structures is an important method to realize vibration reduction and damping. Composite sandwich structures not only possess certain mechanical properties but also offer the advantage of lightweight construction. In this study, based on the composite coupled lattice sandwich structure, the energy transfer at different frequencies is visualized by vibration power flow. We utilize the finite element power flow method to calculate power flow at excitation and response points. We employ the finite element power flow method to calculate the power flow at excitation and response points. By integrating COMSOL Multiphysics and MATLAB, we generate power flow vector diagrams and cloud plots and observe the vibration energy transfer process in the time domain state. The results show that the vibration energy transfer path of the composite sandwich structure becomes complicated with the increase of frequency, and the energy distribution is mainly concentrated at the coupling, demonstrating an excellent vibration attenuation effect.
