| 摘 要： | 为了能够提高单一PVDF压电悬臂梁发电装置的输出特性,提出了改变其悬臂梁刚度的设计。建立了悬臂梁式PVDF压电风能发电装置参数化有限元模型,以风能发电装置输出电压最大化为目标,分别利用序列二次规划算法和自适应模拟退火算法进行了优化设计。基于优化设计的结果,制作了压电风能发电装置样机,并进行了实验,结果表明,当风速在4~14 m/s范围内,优化后的输出电压值均高于优化前以及单一PVDF结构,同时优化后的最大输出功率为优化前最大输出功率的4倍。

| Abstract: | In order to improve the output characteristics of a single PVDF piezoelectric cantilever beam generator,a design of changing the stiffness of the cantilever beam was studied.The parametric finite element model of the PVDF cantilever piezoelectric wind energy generator was established.In order to maximize the output voltage of the wind energy generator,the nonlinear programming by quadratic lagrangian(NLPQL)algorithm and adaptive simulated annealing(ASA)algorithm were used to optimize the design.Based on the results of the optimal design,the piezoelectric wind energy generator prototypes were fabricated and tested.The experimental results show that when the wind speed is in the range of 4~14 m/s,the output voltage value of the optimized structure is higher than that of the initial one and the single PVDF structure.The maximum output power of the optimized structure is 4 times of that of the initial one. |
