Analysis of Mechanical Stress and Magnetic Field in Nuclotron Dipole Magnet for GSI Accelerator

在本论文中,我们发展了磁机械耦合的ANSYS分析方法,使用有限元方法研究了加速器二极磁体的应力特性,通过数值模拟,我们研究了超导加速器磁体在磁体装配,冷却和运行磁场为2T时的应力。研究的结果将用于评估超导加速器磁体在建造和运行时的应力控制。

A mechanical analysis of the Nuclotron dipole magnet is carried out using ANSYS Finite Element Method. It is used to evaluate the stress in the magnet at full field of 2 Tesla. A magneto-mechanical model for the dipole was developed using the program ANSYS and employed to compute the mechanical state of the coil under pressure and under Lorentz forces at nominal field. The results of a parametric study where the dimensions of several components were altered are used to estimate the impact of fabrication tolerances and assembly procedures on the final mechanical state of the magnet.
