Abstract

A smart-structure variant representing a piecewise homogeneous body composed of elastic and viscoelastic materials and piezoelectric elements the electrodes of which can be connected to shunting circuits is considered. One of the basic purposes of such structures is vibration damping. This paper deals with a variant in which the classic resistor in a shunting circuit is replaced by a graphene composite acting not only as a mechanically deformable body, but also as a resistor in a smart structure. The mathematical formulation of the problem of forced steady-state and natural vibrations in the structures composed of elastic and viscoelastic elements, piezoelectric elements, and graphene composites acting as a deformable body and a resistor is given. The results of numerical experiments demonstrate the applicability of graphene composites for implementing an additional mechanism of vibration damping in smart structures based on piezoelectric elements.

石墨烯复合材料在压电结构智能结构附加减振中的应用

摘要

考虑一种智能结构变体，该变体代表由弹性和粘弹性材料以及压电元件组成的分段均质体，其电极可以连接到分流电路。这种结构的基本目的之一是减振。本文讨论了一种变体，其中并联电路中的经典电阻器被石墨烯复合材料代替，该石墨烯复合材料不仅充当机械可变形体，而且还充当智能结构中的电阻器。给出了由弹性和粘弹性元件，压电元件以及充当可变形体和电阻器的石墨烯复合材料组成的结构中的强迫稳态和自然振动问题的数学公式。
