Abstract
The design of the laboratory shaker linear electric drive mechanical part is proposed, its mathematical model is given, and the algorithm for calculating the linear electromagnetic motor’s dynamic characteristics is presented. Computer simulation of the drive is carried out using the COMSOL Multiphysics finite element modeling software. The dynamic operation mode of the motor’s reciprocating motion is studied, and its dynamic (speed-torque) characteristics are given. The study results have shown that the laboratory shaker drive based on a linear electromagnetic motor has properties commensurable with those of the drive for serially produced shakers. Moreover, in regard of certain indicators, such as the maximum oscillation frequency and peak power consumtion, the newly designed drive has better characteristics.
