摘要：设计了颗粒阻尼及磁流变复合减振镗刀的磁抑振单元的磁路，并利用仿真软件ANSYS建立了磁路仿真模型。以正交试验为基础，通过仿真研究了磁路特性、磁场分布规律以及不同参数下阻尼通道的磁感应强度。研究表明，轴肩宽度、支撑套厚度和间隙宽度是影响磁通道磁感应强度的主要因素，可以通过合理选择磁路结构参数使减振性能达到最佳状态。

Abstract:The magnetic circuit of a particle and magnetorheological compound damping boring tool is designed，and the magnetic circuit simulation model is established by using ANSYS software.Based on orthogonal experiment，the characteristics of the magnetic circuit，the distribution of the magnetic field，and the magnetic induction intensity of the damped channel under different parameters are studied by simulation.The experiments show that the axial shoulder width，the support sleeve thickness and the gap width are the main factors affecting magnetic induction intensity of the magnetic channel，and the optimal performance of vibration reduction can be achieved through the reasonable selection of magnetic circuit structure parameters.
