Thus, this paper proposes a phononic-like crystal (PLC) plate model with multiple low-frequency band gaps. This new PLC plate takes into account the elastic constraints of the foundation, external loads, and material damping. The characteristics of band structure and vibration transmission of the new PLC plate structure, and the influences of the coupling effects of the external forces and elastic constraints, and damping ratio of material on characteristics of vibration reduction are analyzed by theoretical calculations in detail.
