Abstract

In this paper, modeling active vibration control for a thin mechanical structure as a cantilever beam with bonded piezoelectric patches is analyzed. The transversal linear force produced by a linear piezo-actuator is replaced by the moment of force produced by the patch piezo-actuator, which is glued to the surface of the thin structure. Beam deflection measurement is replaced by measuring the elongation or shortening of the surface of the deformed beam. To analyze the effect of various controllers on vibration damping, a model using Matlab Simulink is created.

贴片压电致动器在振动主动控制中的应用建模
本文分析了带有粘结压电片的悬臂梁薄机械结构的振动主动控制建模问题。线性压电致动器产生的横向线性力被贴片压电致动器产生的力矩所取代,贴片压电致动器粘接在薄结构表面。梁挠度测量被测量变形梁表面的伸长或缩短所取代。为了分析各种控制器对振动阻尼的影响,利用Matlab Simulink建立了模型。
