Abstract

A dynamic model of ultrasonic vibroimpact treatment is constructed with the use of a vibrational system with two waveguides set with a gap: the one of them is excited by an ultrasonic generator and the other one serves as a passive resonant bearing. The rigid-plastic model is used for the material in the gap. Using the difference in the natural frequencies of the waveguides, the frequency response and the phase response of the vibrational system under loading are computed and the stability regions of the resonating vibroimpact modes are determined. The relation between the dynamic parameters of the ultrasonic vibrational system and the parameters of the vibroimpact deformation of the product is established.

刚性调整间隙的棒形振动冲击系统中超声微锻造的动力学模型

摘要

超声振动冲击治疗的动力学模型是通过使用振动系统构建的,该振动系统具有两个设置有间隙的波导:一个波导被超声波发生器激发,另一个波导用作被动共振轴承。间隙中的材料使用硬塑料模型。利用波导固有频率的差异,计算了振动系统在负载下的频率响应和相位响应,并确定了振动冲击模式的稳定性区域。建立了超声振动系统的动力学参数与产品振动冲击变形参数之间的关系。
