Abstract :
Phononic crystal is a new kind of non-uniform compound material with elastic vibration band gaps where the propagation of vibration is restrained or forbidden. This property provides a new research method for the control of low frequency interior noise. After introducing the interior noise, body ceiling vibration characteristics, establish the FEM of thin phononic crystal; bring up the simplified model of the vibration along Z axis, analysis the influence of the parameters on band gap by using the simplified formula, thus designed phononic crystal for vibration reduction of the body ceiling.
