关 键 词：Periodic tube Piezoelectric phononic crystal Resonant shunting circuit Locally resonant Band gap
摘 要：A tube phononic crystal（PC）model arrayed periodically by metal and piezoelectric segments is *** piezoelectric segment consists of two piezoelectric layers connected in parallel independently by a resonant shunting *** inductor and a piezoelectric equivalent capacitor form an inductor-capacitor *** vibration of extension and flexure of the thin periodic tube structure is studied by the classical shell theory and linear piezoelectric *** electric field method and transfer matrix method are applied to solve band gap structures and transmission factor *** locally resonant band gaps and one Bragg band gap are *** interesting phenomena of interaction between two locally resonant bands are *** effects of circuit inductance,material parameters of the tube PC on these three band gaps are investigated.
