Bending wave vibration reduction structure and system and structural absorption coefficient calculation method thereof

The invention relates to the technical field of vibration reduction, in particular to a bending wave vibration reduction structure and system and a structural absorption coefficient calculation method thereof.The bending wave vibration reduction structure comprises two long-tooth sub-cavities and two short-tooth sub-cavities arranged between the two long-tooth sub-cavities, and the long-tooth sub-cavities and the short-tooth sub-cavities are arranged in the same direction; the bending wave vibration reduction system comprises a main body and a bending wave vibration reduction structure arranged on the main body; according to the bending wave vibration reduction structure, the long-tooth sub-cavities and the short-tooth sub-cavities are sequentially arranged according to the sequence so that one-way bending waves can be absorbed, the bending wave vibration reduction structure is arranged on the main body so that a bending wave vibration reduction system can be obtained, and the bending wave vibration reduction
