摘要: 空间三维椭圆振动切削被认为是难加工材料复杂表面切削极具发展前景的切削方法。采用压电驱动和柔性铰链导向，本文设计了一种新型的空间三维椭圆振动切削装置，并借助有限元方法对装置结构进行了运动学分析和模态分析，仿真分析了结构的运动轨迹和前六阶模态，验证了所设计结构的可行性。
Abstract: For complex surface of refractory materials, three-dimensional elliptical vibration cutting is con-sidered to be a promising cutting method. In this paper, a three-dimensional elliptical vibration cutting device was designed with piezoelectric drive and flexible hinge guidance, and the kine-matics and modal analysis of the structure are carried out with the help of finite element method. The motion trajectory and the first six modes of the structure are simulated and analyzed, and the feasibility of the structure is verified.
