Abstract

The advancement of microelectronics reduces the power of sensors, making it possible to use the ambient vibration to selfsupply the sensors. The mechanical model of a bistable piezoelectric cantilever beam power generation system considering the gravity influence was established, and a dimensionless control equation of the system was obtained. By means of numerical analysis, the influence of gravity on the average output power of the bistable piezoelectric cantilever beam was investigated under the combined excitation of simple harmonic wave and white noise. Combining with the halfpower bandwidth method, the method of determining the minimum influence interval of gravity under white noise excitation was put forward under the premise of ensuring the high power output of the piezoelectric power generation system. The above results can provide references for the related research of piezoelectric power generation systems.
