systems excited by the operation of machines and different mechanisms

Development

of the mechanical, electromagnetic and complex models of the transducer

Simulation of the vibroacoustic transducer in a single software environment COMSOL Multiphysics

is difficult to make a spring with a low coefficient

of elasticity, able to withstand considerable mass with large displacements

It is difficult to make a highly linear electromagnetic system

of the obtained data was performed, as a result of

which an optimal electromagnetic system of a the low-frequency converter was selected, intended for use in ADS
A soft spring was developed, with a low coefficient of elasticity, capable of working on large displacements and withstanding a large mass, while with high linearity (during operation, it practically does not create unwanted side harmonics)
A complex model has been developed for calculating the entire system in which the electrical, magnetic, and mechanical subsystems are interconnected through electro-mechanical coupling coefficients
