Abstract

In the process of studying multiphysical processes, including electrophysical ones, the resonance frequency at which the piezoelectric actuator maximally influences the amplitude of oscillations of the plow blade was established in the COMSOL Multiphysics software package. The maximum amplitude of oscillations of the plow-piezo actuator system and the rational location of the piezo actuator on the dump, which provides an efficient vibration process, have also been dete rmined. The performed numerical experiments allowed to obtain approximation expressions for simplified determination of the amplitude of oscillations of the system depending on the coordinates of the piezo actuator on the heap. The research results can be used in the design of vibrating soil cultivation bodies in agricultural machinery.
