HL-2A装置LHCD新天线热分析和电磁力分析

内容简介：用有限元方法对LHCD天线实际工况条件下的受热情况进行了模拟分析，结果表明无氧铜可满足热对材料的要求。给出了托卡马克环向磁场和等离子体电流变化时天线所受电磁力的解析与数值结果，论证了对天线起破坏作用的是等离子体破裂时由一对扭力所产生的扭矩，不锈钢更满足扭力对材料的要求。实际加工过程中使用无氧铜和不锈钢相结合的方式是比较合理的。该工作为天线的研制提供了理论指导。

Abstract：A new LHCD antenna has been designed for HL-2A tokamak in passive active multijunction (PAM) form. Thermal analysis of the antenna has been done by finite element method,which shows that oxygen free copper can meet the thermal requirements. Electromagnetic analysis is carried out by analytic method under varying toroidal magnetic field and plasma current conditions. It is demonstrated that a pair of torque generated by the electromagnetic torsion may destroy the antenna when plasma disrupts, and stainless steel can satisfy the torque requirements. Combining oxygen free copper and stainless steel may be a reasonable solution in the practical manufacturing process. This work provides theoretical basis for the development of the new antenna.
