[Magnetic Field - Thermal - Structural Coupling Case] Volume 1: Analysis of High Magnetic Field Generation by Coil Method

Calculated up to 3 μsec! The analysis results and experimental results for the magnetic field generated at the center of the coil match well!

By utilizing the magnetic field analysis function available from LS-DYNA Ver.R7, it is possible to conduct a magnetic field-thermal-structural coupled analysis considering large deformations of coils using only "LS-DYNA." The coil in this case study is made of copper, and calculations were performed up to 3 microseconds. In the analysis, the electrical conductivity of copper is approximated using the Burgess model, which takes into account the electrical conductivity of copper in both solid and liquid states as implemented in this product. 【Case Overview】 ■ Magnetic field generated at the center of the coil - The analysis results align well with the experimental results. - It is evident that LS-DYNA's magnetic field-thermal-structural coupled analysis is highly accurate. ■ Deformation process of the coil and temperature distribution - There are areas that significantly exceed the melting point of copper (1358K), but in the analysis, these are considered in a liquid state, and the electrical conductivity in that state is taken into account. *For more details, please refer to the related links or feel free to contact us.
