摘要
利用ANSYS分析软件对矩形微悬臂梁进行模拟仿真分析,得出微悬臂梁的振型、固有频率及其在外加负载时的电压输出。在此基础上,设计、制作了微悬臂梁及能量存储电路,并在低频下对微悬臂梁的发电性能进行了测试。结果表明,当负载电阻为1 k时,此时的瞬时输出功率最大可达到0.077 4 W,可以满足低功耗产品的供电需求。
A rectangular micro cantilever beam was simulated and analyzed by ANSYS software, the micro cantilever beam＇s vibration mode, inherent frequency and the voltage output under external loads were get out. Based on the above, the micro cantilever beam and the energy storage circuit were designed and produced, and the electricity generating performance of the micro cantilever beam was tested under low frequency. The results show that when the load resistance is 1 kΩ, the maximum instantaneous output power is 0.077 4 W, which can meet the power supply requirements of low power consumption products.
