Method for vibrating power-generation analysis finite element by different shapes of cantilever beam piezoelectric vibrators

The invention discloses a method for vibrating a power-generation analysis finite element by different shapes of cantilever beam piezoelectric vibrators. The method comprises the following steps: utilizing soliworks software to respectively establish geometric models of rectangular, trapezoidal and triangular cantilever beam piezoelectric vibrators of which the length, the thickness and the root width are all equal through approximate simplification; respectively leading the geometric models into ansys software and implementing the following operational steps: S1: setting and distributing material properties and cell types of all parts of piezoelectric vibrators; S2: setting meshing properties and carrying out the meshing by adopting a mapping mode; S3: setting boundary conditions and voltage coupling restrains and establishing a finite element model of the cantilever beam piezoelectric vibrators; S4: utilizing the ansys software to apply a fixed load to the cantilever piezoelectric vibrators, carrying out st
