摘要
Abstract
The magnetic resonance pole head structure with high uniformity of the initial magnetic field was designed by finite element optimization method.Firstly,parametric modeling and simulation are carried out on the parameters that need to be optimized for the pole head of the normal conductor,and the response surface optimization method in the optimization method is used to optimize the pole head structure of the normal conductor;the initial magnetic field uniformity of the magnet before optimization is 7.811 Gs,and the initial magnetic field uniformity after optimization is 0.751 Gs,which is improved by 10.4 times.The pole head structure of the normally conducting magnet based on finite element response surface optimization meets the design requirements,can effectively improve the uniformity of the initial magnetic field,and provides a design method for the optimal design of the normally conducting magnet structure.关键词
