In this paper, based on the numerical solution to the problem of forced steady-state vibrations of piecewise homogeneous electro viscoelastic bodies, an analysis of the mechanical response of a system to the action of a number of parameters characterizing the applied mechanical or/and electrical action was carried out. The object of research was a cantilever rectangular plate with a piezoelectric element located on its surface. Functional relations that allow determining optimal parameters of electrical impact providing minimal value of a mechanical response were obtained for cases of action of two loading factors. A condition was established that allows reaching such a result: the resulting responses in case of action of a single load factor should be equal and loads must be applied in opposite phase. © 2023 The Authors.

Introduction Dynamic external influences on mechanical structures cause their vibrations, which may be undesirable or even dangerous, leading to damage, malfunctions, and the appearance of noise. This problem appears in a wide range of structures, such as buildings, bridges, aerospace systems, industrial machines, precision tools, robotic manipulators and others. Therefore, it is natural for researchers to control the dynamic behavior of structures, minimizing undesirable effects on structures. Currently, one of the promising areas of development in high-tech fields of
