| 摘要：电磁夹具是当今工装夹具的发展趋势所向，其具备传统组合夹具所不具备的优点，针对电磁夹具的设计与研究，本文展开了以下工作： 1.基于电磁场的理论研究，选择通电线圈作为磁场激励源，对单个通电线圈和多个通电线圈的外部磁场特性进行了理论研究。 2.对单个通电线圈周围产生的磁场、多个单列通电线圈组合产生的磁场情况进行了ANSYS仿真分析，得出了此两种磁场强度分布情况的结果和磁场激励特征。 3.基于以上两部分计算与仿真，为电磁夹具设计磁场激励情况提供了一般结论与参考。研究结果表明：单个线圈产生的磁场覆盖范围有限，为了满足在更大的范围内产生磁场，通常需要将多个通电线圈按照某些顺序排列起来，每个线圈产生的磁场在空间中进行叠加，从而增加磁感应强度并提高磁场的均匀程度；相邻两线圈的磁场激励电流反向时，产生的磁场更均匀。 4.总结与展望部分，采用数值算法可以进一步提升电磁夹具设计仿真研究的计算精度；还可以对更多通电线圈不同的几何排列情况下，进行仿真研究。35709 毕业论文关键词： 电磁夹具；通电线圈；ANSYS；仿真 Abstract：Electromagnetic fixture is the current development trend of fixture which has the advantages that traditional one do not have, according to the design and research of electromagnetic fixture, this paper carried out the following work: 1 Based on the theoretical research of the electromagnetic field, select the coil magnetic field as the excitation source, single coil and a plurality of coils of the external magnetic field is studied theoretically. 2 Make ANSYS simulation analysis on magnetic field produced by the single coil and more than a single coil, obtained the two kinds of magnetic field intensity distribution and characteristics of magnetic field excitation. 3 Based on the above two parts of calculation and simulation, provides a general conclusion and reference for the fixture design of electromagnetic field excitation. The results show that: single coil magnetic field generated by the limited coverage, in order to meet the magnetic field generated in a larger range, usually need more than one coil according to certain order, each coil generates a magnetic field superposition in space, thereby increasing the magnetic induction intensity and increase uniformity of magnetic field; two adjacent coil magnetic field excitation current is reversed, the magnetic field generated by a more uniform. 4 Summary and prospect, calculation accuracy using the numerical algorithm can further enhance the research on electromagnetic fixture design simulation; can also be different for more geometric coils arranged in case, simulation research.
