【摘要】：隨著電子技術(shù)的高度發(fā)展，，電子元件的功耗不斷降低，使自供電的能量收集器的應(yīng)用成為可能。振動(dòng)作為一種清潔、可再生、且普遍存在的能源近年來受到人們?cè)絹碓蕉嗟年P(guān)注，基于振動(dòng)的能量收集技術(shù)因其廣闊的應(yīng)用前期也得到迅速發(fā)展。 本文針對(duì)振動(dòng)能量特點(diǎn)和對(duì)壓電、電磁能量收集技術(shù)的研究，設(shè)計(jì)了一種內(nèi)沖擊型壓電電磁復(fù)合式振動(dòng)能量收集器，并通過實(shí)驗(yàn)和理論分析，研究電機(jī)性能，結(jié)果表明沖擊型結(jié)構(gòu)和多模式能量收集方式可以顯著提高電機(jī)的能量收集性能。 因?yàn)檎駝?dòng)能量收集器收集的能量相對(duì)過小，不能直接給電子元件供電，因此需要采用儲(chǔ)能電路對(duì)收集到的能量進(jìn)行存儲(chǔ)再利用。這里我們主要研究了振動(dòng)發(fā)電機(jī)的壓電部分，找出壓電振動(dòng)發(fā)電機(jī)正確的等效電路模型并通過PSPICE電路仿真軟件進(jìn)行建模計(jì)算，結(jié)合實(shí)驗(yàn)找出電機(jī)最佳儲(chǔ)能電容，并分析模型中各個(gè)參數(shù)對(duì)最佳儲(chǔ)能電容的值的影響。 后來我們又對(duì)內(nèi)沖擊型壓電振動(dòng)發(fā)電機(jī)進(jìn)行深入研究，主要分析了非均勻厚度懸臂梁結(jié)構(gòu)，設(shè)計(jì)了3種不同拓?fù)浣Y(jié)構(gòu)的懸臂梁結(jié)構(gòu)并通過實(shí)驗(yàn)和有限元仿真分析，研究各個(gè)結(jié)構(gòu)的能量收集性能，得到非均勻厚度懸臂梁能顯著提高電機(jī)性能。
[Abstract]:With the rapid development of electronic technology, power electronic components continue to decrease, the application of self energy collector power supply possible. Vibration is a kind of clean, renewable energy, and widespread in recent years has attracted more and more attention, the vibration energy harvesting technology because of its wide application has also been developed rapidly. Based on the previous
According to the characteristics of piezoelectric vibration energy and electromagnetic energy collection technology, research, design a kind of internal impact type piezoelectric composite electromagnetic vibration energy collector, and through experiments and theoretical analysis, the research results show that the motor performance, impact structure and multi mode energy collecting method can significantly improve the performance of motor energy collection.
Because the collection of vibration energy collector energy is too small, not directly to the power supply of electronic components, so it is necessary to adopt a storage circuit to collect the energy storage and utilization. Here we mainly study the piezoelectric vibration generator part, find out the pressure equivalent circuit model of electric vibration generator right and through the PSPICE circuit simulation software for modeling according to the experimental calculation, find out the best motor capacitor, and analysis of various parameters in the model on optimal storage capacitor value.
We then the impact type piezoelectric vibration generator are studied, the main analysis of the non-uniform thickness of cantilever beam structure, designed 3 kinds of different topology cantilever beam structure by experiments and finite element simulation analysis, energy harvesting performance of each structure, non uniform thickness of cantilever beam can significantly improve motor performance.
