超声珩磨颤振单颗磨粒动力学模型的研究

摘要

Chatter is one of the important factors that affect grinding stability and processing quality, dynamic model is usually used to study the stability of ultrasonic honing. In the basis of proposing the basic assumptions on the single Abrasive grain and analysis the mechanism of regenerative chatter, establish three-dimensional and multi-freedom degree of nonlinear dynamic model of ultrasonic honing The dynamic models and equations of single grain in the axial and radial ultrasonic vibration honing was simplified, and provided a basis for to further explore effective methods of suppress and eliminate vibration.%颤振是影响磨削加工稳定性及加工质量的重要因素之一,对于超声珩磨稳定性的研究主要通过动力学模型.在提出对超声珩磨单颗磨粒的基本假设和分析再生型颤振产生机理的基础上,建立了超声珩磨颤振单颗磨粒三维多自由度非线性动力学模型,并简化了轴向和径向超声振动单颗磨粒的动力学模型及其方程,为进一步探求有效的抑振、消振方法提供了依据.
