It has the advantages of high sensitivity, wide frequency band, high signaltonoise ratio, simple in structure, and reliable lightweight etc. And the piezoelectric sensors are constantly to intelligent development.This paper introduces the basic theory of piezoelectric sensors which are piezoelectric effect, piezoelectric materials, piezoelectric equation and piezoelectric sensor equivalent circuit. Then it introduces two kinds of piezoelectric sensors. One is PDVF piezoelectric sensor which is made by a new type of piezoelectric materials. It respectively explains the advantages of PDVF film, piezoelectric properties, cosine and sine PDVF piezoelectric sensor and the use of measuring vibrates beam. Another is IEPE piezoelectric sensor, including acceleration sensor accelerated the advantages, working principle and the application of vibration pacting roller test.Keywords：piezoelectric sensor, IEPE acceleration, acceleration sensor, PDVF film目 錄第 1 章 緒論 ...........................................................................................................................................1 壓電傳感器的特點(diǎn)及發(fā)展 ...........................................................................................................1 壓電傳感器的國內(nèi)外發(fā)展現(xiàn)狀 ...................................................................................................1 智能傳感器的產(chǎn)生與發(fā)展前景 .....................................................................................................2第 2 章 壓電傳感器的理論基礎(chǔ) ...........................................................................................................4 壓電傳感器的基本特性 .................................................................................................................4 壓電效應(yīng) ..................................................................................................................................4 壓電材料 ..................................................................................................................................5 壓電方程與壓電常數(shù) ..............................................................................................................5 壓電式傳感器的等效電路 .............................................................................................................8 壓電式傳感器的信號變換電路 .....................................................................................................9 變換電路的必要性 ..................................................................................................................9 電壓放大器 ............................................................................................................................10 電荷放大器 ............................................................................................................................12第三章 PDVF 壓電傳感器 ....................................................................................................................13 PVDF 壓電薄膜 ..........................................................................................................................13 PVDF 壓電薄模的壓電方程 ................................................................................................13 PVDF 壓電薄膜制作傳感器的理論分析 .............................................................................14 PVDF 壓電傳感器的設(shè)計(jì) ............................................................................................................17 梁的彎曲波 ...........................................................................................................................17 振動(dòng)粱的基本物理量 ............................................................................................................19 傳感器的設(shè)計(jì) ...............................................................................................................................19 形狀設(shè)計(jì) ...............................................................................................................................19 正弦傳感器的設(shè)計(jì) ................................................................................................................20 余弦傳感器的設(shè)計(jì) ...............................................................................................................20 正余弦傳感器測量物理量的原理 ...............................................................................................22第四章 壓電加速傳感器 .......................................................................................................................24 壓電式加速度傳感器的基本概念 ...............................................................................................24 加速度傳感器的工作原理 ...........................................................................................................24 IEPE 加速計(jì) ..................................................................................................................................25 IEPE 加速計(jì)的工作原理 ......................................................................................................26 IEPE 加速計(jì)的優(yōu)點(diǎn) ..............................................................................................................26 壓電加速傳感器在振動(dòng)測量中的應(yīng)用 .......................................................................................27 壓電式加速計(jì)的測振原理 ....................................................................................................27 用壓電式加速度傳感器的振動(dòng)測試方案 ............................................................................28 振動(dòng)壓路機(jī)振動(dòng)的測量 ...................................................................................
