 The Pyramid lattice core sandwich plates have been gaining popularity in recent years due to their ability to reduce vibrations. To improve upon this technology, researchers have developed a new sandwich pyramid lattice core with resonant rings, SBLCRR, which has shown great promise in terms of its ability to suppress vibrations. This new design was tested using both finite element analysis and experiments, and it was found that the SBLCRR can effectively block certain frequencies of vibration while allowing others to pass through. Additionally, the geometry, material properties, and period parameters of the SBLCRR were studied and analyzed to determine how they affect the overall performance of the device.
