Piezoelectric material is a kind of material that can perform electric-force conversion. Various actuators made of its inverse piezoelectric effect have been widely used in intelligent structures. In this paper, a piezoelectric actuated turbulence generator is designed, the design concept and working principle are introduced, the mechanical behavior of the piezoelectric structure is analyzed by using the finite element method, and the influence of electrical load on the deformation of the piezoelectric structure along different directions is considered. This paper can provide some theoretical basis for the design and analysis of turbulence generator.
