Abstract
The aim of the thesis is to study the potential and kinetic energy transformation mechanism of bistable snapping spring sheet, and to design a piezoelectrical actuator system and an electricity generation system by combining the energy transformation mechanism with piezoelectrical elements. The first step is to analyze the relationship between the applied force and the deformation of the bistable snapping spring sheet by theories and the finite element method, and to find out influence parameters of design and operation. Then, experiments will be accomplished to verify the analysis result. By means of combining characteristic large force and small deformation of piezoelectrical element with the characteristic high-speed and large deformation of bistable snapping spring sheet, a piezoelectrical actuator system can be developed to produce a large deformation. In respect of electricity generation system, an inductance coil type electricity generation system and a piezoelectrical electricity generation system will be tested separately. Finally, the electricity generation system will be combined with a commercial radio frequency transceiver to test the actual effects of generating electricity.
