水冷磁体容器的结构设计与强度分析

Structural Design and Strength Analysis of Water-Cooled Magnet Vessel

为建造稳态强磁场水冷磁体实验装置,对水冷磁体容器进行了结构设计.设计中,容器的封盖采用三层环形钢板叠加焊接而成,采用双层筒体,即内筒体与外筒体,并由上下两部分组成.用三维绘图软件Solidworks设计出容器的结构模型,采用有限元分析方法,将容器的结构模型转入到COSMOSWorks平台,对容器进行应力与位移的分析计算,按照压力容器的设计规范,对容器的各类应力进行了应力强度评定.计算结果显示,容器的最大位移为0.499 mm,容器的强度、位移和安全性满足设计要求.

In order to build steady high magnetic field experimental devices of water-cooled magnets,a structural design was made for a water-cooled magnet vessel.In the design plan,the capping was composed of three circular steel plates which were welded in the superimposed form,and the cylinder consisted of two layers： the inside cylinder and the outside cylinder,each including the upper and lower parts.The structural model of the vessel,designed by the three-dimensional drawing software Solidworks,was transferred to COSMOSWorks for the finite element analysis of stress and displacement.According to the design standards of pressure vessels,various kinds of stresses of the vessel were assessed by the stress intensity estimation criteria.The results show that the maximal displacement of the vessel was 0.499 mm,and the strength,displacement and security of the vessel met the design requirements.
