摘要

为了研究一阶、二阶模态下，压电单晶悬臂梁振动发电机陶瓷片最佳贴片位置，利用欧拉伯努利梁模型，讨论了一阶与二阶模态下陶瓷片最适宜的贴片位置，并通过电机开路电压、短路电流及LED照明试验，得到了最佳贴片位置。在一阶模态时，陶瓷片贴于悬臂梁根部的电机能够获得最大的发电量，通过对4种不同贴片位置电机的发电试验分析，陶瓷片贴于根部的电机开路电压及短路电流分别是其他电机的4倍以上，其驱动的LED功率为其他电机的10倍以上。而对于二阶振型，陶瓷片贴于悬臂梁中间位置的电机发电量最大，贴于根部位置的电机次之，6种不同贴片位置电机的发电试验表明，前者开路电压、短路电流分别为后者的1.2倍和1.9倍以上，两者驱动的LED功率相差1.4倍以上。试验结果与计算结果均表明：一、二阶模态时悬臂梁最佳贴附位置分别是根部和中间位置，需根据不同振型选择陶瓷片最佳粘贴位置。

Abstract

In order to find the most appropriate location of the piezoelectric ceramics patch under the first and second vibration modes

the position of piezoelectric patch is discussed in the first and second modes with Euler-Bernoulli model. Through testing the open circuit voltage

short-circuit current of generator and the performance of LED lighting

the best position of the ceramics patch is obtained. When the piezoelectric ceramics patch locates at the root of cantilever

generator shows the best performance under the first vibration mode. Compared with experimental data of other three generators

opening voltage and short current are 4 times higher and LED power is 10 times higher. Moreover

generation ability is investigated under the second vibration mode. When ceramics patch respectively locates at the middle and the root of cantilever

the generation performance of the former is superior to the latter. Opening voltage and the short current of the former are 1.2 and 1.9 times higher respectively through six generators experiment. In addition

LED power of the former is 1.4 times more than that of the other. In order to improve generation efficiency

piezoelectric ceramics patch should be located at the root of beam under the first vibration mode. Nevertheless

piezoelectric ceramics patch should be located at the middle of beam under the second mode.
