【正文】 發(fā)電的研究在日本及歐美等國家開始比較早，而國內(nèi)對(duì)壓電發(fā)電的研究尚處于起步階段。居里和 P 近年來利用壓電材料進(jìn)行能量收集的研究越來越受到人們關(guān)注，其節(jié)能環(huán)保的特性也備受人們的青睞。 潮汐發(fā)電，就是利用海水漲落及其所造成的水位差來推動(dòng)水輪機(jī)，再由水輪機(jī)帶動(dòng)發(fā)電機(jī)來發(fā)電。地球上廣大連續(xù)的水體叫做海洋，海洋的面積約為 億 km2，占地球表面積的 ％。利用生物質(zhì)本身的能量，將其轉(zhuǎn)化為可驅(qū)動(dòng)發(fā)電機(jī)的能量形式，如燃?xì)?、燃油、酒精等，再按照通用的發(fā)電技術(shù)發(fā)電，然后直接提供給用戶或并入電網(wǎng)提供給用戶。由于風(fēng)能是隨機(jī)性的，風(fēng)力的大小時(shí)刻變 ， 必須根據(jù)風(fēng)力大小及 電能需要量的變化及時(shí)通過控制裝置來實(shí)現(xiàn)對(duì)風(fēng)力發(fā)電機(jī)組的啟動(dòng)、調(diào)節(jié) (轉(zhuǎn)速、電壓、頻率 )、停機(jī)、故障保護(hù) (超速、振動(dòng)、過負(fù)荷等 )以及對(duì)電能用戶所接負(fù)荷的接通、調(diào)整及斷開等操作。 到處陽光到處電 是倡 導(dǎo)利用綠色能源的主題。 第 1 章 緒論 ................................................................................................................ 1 課題背景 ........................................................................................................... 1 壓電發(fā)電的概況及應(yīng)用 ................................................................................... 2 壓電發(fā)電的概況 ........................................................................................ 2 國外壓電發(fā)電的應(yīng)用 ................................................................................ 3 論文研究內(nèi)容 ................................................................................................... 6 第 2 章 壓電發(fā)電技術(shù) ................................................................................................ 7 壓電振子分析 ................................................................................................... 7 壓電材料與壓 電效應(yīng) ................................................................................ 7 壓電振子 .................................................................................................... 9 壓電振子支撐及激勵(lì)方式 .......................................................................11 壓電發(fā)電裝置結(jié)構(gòu)設(shè)計(jì) ................................................................................. 15 電源控制電路設(shè)計(jì) ......................................................................................... 16 本章小結(jié) ......................................................................................................... 17 第 3 章 壓電振子實(shí)驗(yàn)分析 ...................................................................................... 18 實(shí)驗(yàn)設(shè)備 ......................................................................................................... 18 矩形壓電振子實(shí)驗(yàn)分析 .......................................................................... 18 結(jié)構(gòu)參數(shù)對(duì)矩形壓電振子輸出功率的影響 .......................................... 18 壓電振子厚度對(duì)功率輸出特性的影響 .................................................. 18 厚度比值對(duì)功率輸出的影響 .................................................................. 19 壓電振子長度對(duì)功率輸出的影響 .......................................................... 20 壓電晶片寬度對(duì)功率輸出特性的影響 .................................................. 21 振幅對(duì)壓電振子輸出功率的影響 .......................................................... 21 本章小結(jié) ......................................................................................................... 22 第 4 章 壓電發(fā)電裝置在溫度傳感器中的應(yīng)用 ...................................................... 23 溫度傳感器的設(shè)計(jì) ......................................................................................... 23 溫度傳感器的概況及應(yīng)用 ...................................................................... 23 溫度傳感器的種類與測溫范圍 .............................................................. 25 PN 結(jié)溫度傳感器 ..................................................................................... 26 壓電發(fā)電一體化溫度傳感器的設(shè)計(jì) ............................................................. 28 本章小結(jié) ......................................................................................................... 30 結(jié)論 ............................................................................................................................ 31 致謝 ............................................................................................................................ 32 xx 大學(xué)學(xué)士學(xué)位論文 IV 參考文 獻(xiàn) .................................................................................................................... 33 附錄 A ........................................................................................................................ 35 附錄 B ........................................................................................................................ 41 xx 大學(xué)學(xué)士學(xué)位論文 1 第 1章 緒論 課題背景 近年來， 新能源發(fā)電技術(shù) 被利用率越來越高，其污染小，發(fā)電源多的特點(diǎn)，在很多領(lǐng)域起了很重要的作用。 followed by the use of piezoelectric materials piezoelectric power generation device structure is simple, low cost, easy to implement, may be smaller. But the use of piezoelectric power generation device for each action there is limited capacity and so on, thereby restricting its application in practice. From abroad on the piezoelectric material of the study found that the impact of its generating capacity by many factors, how to optimize these factors. Piezoelectric generation of basic research work is mainly from the characteristics of piezoelectric ceramic materials, as well as the impact of factors such as powergenerating capacity of its aspects, these theoretical studies to solve the piezoelectric ceramic material in the practical application of theoretical issues, as well as piezoelectric ceramic materials in a broader scope of application to lay a solid foundation. Study of piezoelectric power generation in Japan and Europe and the United States and other countries started relatively early, while the domestic research on the piezoelectric power generation is still in its infancy. This article focuses on generating piezoelectric temperature sensor, in an analysis of piezoelectric vibrator of the piezoelectric effect is described and the piezoelectric material. Piezoelectric vibrator through experimental analysis, research on the piezoelectric oscillator output power of the impact of various factors. And with the position of the L44 and D475 rectifier filter circuit posed of piezoelectric control circuit to collect the electricity generating device and electrical applications in temperature sensors
