摘要

在考虑技术负荷的情况下，采用原始方法建立数学模型来研究低频电振动机械的动力学。在对描述电磁激振器振荡运动的微分方程进行数学分析的基础上，对现有的数学模型进行了修正，以描述半导体二极管在单周期振动器功率电路中的作用。对非线性动态系统建模揭示了获得驱动力频率的相关离散变化的幅频特性的困难，以及克服这些困难的方法。

SOME PROBLEMS WITH THE MATHEMATICAL MODELING OF ELECTROMAGNETIC VIBRATORS USED FOR TRANSPORTING BULK MATERIALS

Mathematical modeling with the original approach is used to study the dynamics of low-frequency electro-vibration machines while taking the technological load into account. Based on the mathematical analysis of differential equations describing the oscillatory motion of electromagnetic vibration exciters, the existing mathematical model has been corrected to describe the action of a semiconductor diode in the power circuits of single-cycle vibrators. Modeling nonlinear dynamic systems reveals the difficulties of obtaining the amplitude-frequency characteristics of the associated discrete change in the frequency of the driving force, as well as ways to overcome them.
