Abstract: Abstract. The purpose of the article is to improve the design of a screw linear piezoelectric motor as a result of the use of bimorph piezoelectric elements, which made it possible to reduce the length of the stiffening ribs of the entire structure. For research, mathematical modelling was used in the environment of the COMSOLMultiphysics software package, taking into account the relationship between electrostatic and mechanical phenomena. By means of numerical simulation, natural vibration frequencies of the design of a linear ultrasonic motor with bimorph piezoelements are determined. Using the graph of the amplitude-frequency characteristic, the main resonant frequency of the piezoelectric motor is determined. An experimental sample of a screw linear piezoelectric motor was also made, which demonstrated its operability and proved the adequacy of the proposed technical solutions. By conducting experimental studies on the removal of the real amplitude-frequency characteristic of the engine, the validation of the results of numerical experimentswas carried out. The data obtained can be used in the design of devices that use piezoceramic actuators, in particular, in the agricultural sector.
