基于钴铁氧体的双弯超声椭圆振动切削装置研究
Research on a Cobalt Ferrite-Based Dual-Bending Ultrasonic Elliptical Vibration Cutting Device
摘要
Abstract
This study proposes a design method for a dual-bending ultrasonic elliptical vibration cutting(UEVC)device based on cobalt ferrite giant magnetostrictive material,aiming to overcome the issues of aging and overheating failure associated with piezoelectric ceramic actuation.Based on Timoshenko beam bending theory,a high-precision elliptical trajectory output at the tool tip was achieved through a symmetrical fifth-order bending vibration mode combination and nodal fixation technique.The frequency difference between the Z and Y directional vibrations was only 7 Hz,meeting the requirements for synchronous frequency excitation.The de-vice employs a permanent magnet bias field in a collaborative design,combined with a manganese-zinc ferrite closed magnetic circuit,achieving a magneto-mechanical coupling coeffivient of 92%and maintaining a stable operating temperature below 60℃.Dynamic and magnetic circuit optimizations were conducted using ANSYS and COMSOL Multiphysics software.Prototype testing revealed a resonance frequency of 45.43 kHz and a tool tip amplitude of 1.8 μm.Phase-shift cutting experiments confirmed that at a phase difference of 60°,the sur-face roughness was minimized,reducing by 57%compared to that from the conventional cutting,with a uniform and defect-free machined surface.关键词
