摘　　要：功率超声振动珩磨颤振直接影响工件的表面质量和加工精度。以超声珩磨油石为研究对象,建立了超声珩磨再生型颤振的二自由度动力学模型,获得了极限稳定条件;基于Matlab软件分别分析了主轴转速、固有频率、刚度、阻尼比、径向力系数、往复速度、超声振幅、超声频率对超声珩磨稳定性的影响规律。研究有助于抑制或避免珩磨颤振的发生。The chatter of power ultrasonic vibration honing directly affects surface quality and machining accuracy of the workpiece. With ultrasonic honing stone as the research object, two dimensional dynamic models of ultrasonic honing regenerative chatter are established. The ultimate stable conditions are obtained. The spindle speed, natural frequency, stiffness, damping ratio, radial power factor, reciprocating speed, ultrasonic amplitude and ultrasonic frequency are analyzed by Matlab software. These results help to inhibit or prevent the occurrence of honing chatter.
