單個線圈產生的磁場覆蓋范圍有限,為了滿足在更大的范圍內產生磁場,通常需要將多個通電線圈按照某些順序排列起來,每個線圈產生的磁場在空間中進行疊加,從而增加磁感應強度

摘要:電磁夾具是當今工裝夾具的發展趨勢所向,其具備傳統組合夾具所不具備的優點,針對電磁夾具的設計與研究,本文展開了以下工作:
1.基于電磁場的理論研究,選擇通電線圈作為磁場激勵源,對單個通電線圈和多個通電線圈的外部磁場特性進行了理論研究。
2.對單個通電線圈周圍產生的磁場、多個單列通電線圈組合產生的磁場情況進行了ANSYS仿真分析,得出了此兩種磁場強度分布情況的結果和磁場激勵特征。
3.基于以上兩部分計算與仿真,為電磁夾具設計磁場激勵情況提供了一般結論與參考。研究結果表明:單個線圈產生的磁場覆蓋范圍有限,為了滿足在更大的范圍內產生磁場,通常需要將多個通電線圈按照某些順序排列起來,每個線圈產生的磁場在空間中進行疊加,從而增加磁感應強度并提高磁場的均勻程度;相鄰兩線圈的磁場激勵電流反向時,產生的磁場更均勻。
4.總結與展望部分,采用數值算法可以進一步提升電磁夾具設計仿真研究的計算精度;還可以對更多通電線圈不同的幾何排列情況下,進行仿真研究。35709

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. 源¥自%六^^維*論-文+網=www.aftnzs.live
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.
Keywords:Electromagnetic fixture; Electric coil; ANSYS; Simulation
