| 压电堆具有体积小、频响快、能耗低以及集传感与驱动于一体等优点。结合二次驱动机械设计原理,开发了适应于结构振动控制的压电套筒式拉压双向受力主动杆件。本文介绍了主动杆件的设计方法及构成部件,并给出了详细的工作原理图,阐述了主动杆件为充分发挥压电堆良好受压性能而将拉力转化为压力的传力途径,并运用Hamilton原理,对主动杆件进行了有限元建模。通过对压电堆的性能测试,得到了压电堆的电压-位移输出关系以及动态性能曲线;通过对压电主动杆件的动力性能测试,得出压电主动杆件适宜于在20Hz~50Hz频段范围内工作;由驱动性能测试,得到了主动杆件的增益函数。本文结论可为进行结构抗振提供设计参考。 |

| Piezostack possesses many advantages, such as small volume, quick frequency response, low energy consumption and integrated sensing and driving etc. A new telescope-feed tension and compression bidirectional force piezoelectric driving lever adapted to structure vibration control was developed, based on mechanical design principle. This article introduces the design and structural components of piezoelectric driving lever, and presents a detailed working principle diagram, then expounds the load transfer way (from pulling force to pressure) of this new type driving lever. Based on Hamilton principle, finite element model of driving lever was established. Through piezostack performance test, its voltage-displacement output relation and dynamic performance curve are obtained. Dynamic performance test shows that piezoelectric driving lever is suitable for working within 20Hz-50Hz frequency range. Driving lever gain function is obtained from driving performance test. Above results may provide a design reference for structural antivibration. |
