Abstract

The mathematical model of the experimental stand for vibration damping is described in the article. A vibration table is used as a source of vibration of different frequencies. Asynchronous motors are attached to the vibrating table from below. These motors are frequency-controlled and have eccentric disks on the shafts. Due to imbalance, the motors create a vibration that is transmitted to the upper table through the samples of the damping devices being examined. The upper table is equipped with the measuring equipment. Additional sources of vibration are the harmonic components of the voltage generated by power electronic converters at the terminals of the stators of two asynchronous motors. Modeling allows obtaining quantitative characteristics of the studied devices damping in wide ranges of material properties, geometric parameters and control algorithms. The mathematical model of a mechanical system is based on the Lagrange equations and electromechanical energy conversion by electric motors. This model allows for analyzing various options of dampers with various external and control impacts.

在实验装置上进行阻尼器仿真试验

本文描述了减震试验台的数学模型。振动台作为不同频率的振动源。异步电动机从下面连接到振动台。这些电机是变频控制的，轴上有偏心盘。由于不平衡，电机产生振动，该振动通过正在检查的阻尼装置的样品传递到上面的工作台。上台面设有测量设备。另外的振动源是由两个异步电动机定子两端的电力电子变流器产生的电压的谐波分量。建模允许在广泛的材料特性、几何参数和控制算法范围内获得所研究器件阻尼的定量特性。机械系统的数学模型是建立在拉格朗日方程和电动机机电能量转换的基础上的。该模型允许分析具有各种外部和控制影响的各种阻尼器选项。
