介绍了一种超声椭圆振动鞋的设计及其在超声椭圆振动鞋无心磨削中的应用。首先，从固定支承的角度讨论和确定了鞋的弯曲方向和纵向的振动模式。然后通过有限元分析确定了鞋的结构和尺寸。为了明确所生产的鞋的性能，建立了一套评价装置。利用激光测振仪对不同外加电压下的椭圆运动进行了研究。最后，进行了工件回转运动控制试验和实际磨削作业。结果表明，随着外加电压的变化，工件转速呈线性变化。这表明，通过鞋的椭圆运动可以精确控制工件的回转运动。此外，磨削后的工件圆度从初始值25微米明显提高到最终的0.64微米，表明所生产的鞋底在实际磨削作业中表现良好。
We describe the design of an ultrasonic elliptic-vibration shoe and its performance in ultrasonic elliptic-vibration-shoe centerless grinding. First, the vibration modes of the shoe for the bending and longitudinal directions are discussed and determined from the point of view of fixing the support of the shoe. Then the structure and dimensions of the shoe are determined by FEM (Finite Element Method) analysis. In order to clarify the performance of the produced shoe, an evaluation apparatus is built. The elliptic motions under different applied voltages are investigated using laser vibrometers. Finally, workpiece rotational motion control tests and actual grinding operations are carried out. As a result, it is clarified that the workpiece rotational speed changes linearly with variation of the applied voltage. This indicates that the workpiece rotational motion can be precisely controlled by the elliptic motion of the shoe. In addition, the workpiece roundness was clearly improved from an initial value of 25µm to a final value of 0.64µm after grinding, indicating that the produced shoe performed well in actual grinding operations.
