摘　　要：基于对电磁力以及热应力的解析计算公式的推导,运用ANSYS有限元仿真软件对固定电抗器顶底端面情况下的铜箔进行电磁-温度-结构耦合分析,分别得出热应力及所受总应力与应变的分布情况。进一步对电抗器的结构进行优化,综合考虑其结构强度要求与连发温度要求,确定电抗器的最优设计结构,最终通过试验验证出仿真与设计方案真实可信。Based on the derivation of analytical formulae for electromagnetic force and thermal stress,ANSYS finite-element simulation software was used to analyze the electromagnetic-temperature-structure coupling of copper skin at the fixed top and bottom end surface.The distribution of thermal stress and the total stress and strain were obtained.The structure of reactor was further optimized,and the optimum design of the reactor was determined by taking the structural strength requirements and the temperature requirements into consideration.The credibility of simulation and design solution was verified by carrying out a test.
