利用数值模拟法对缩尺A P1000空槽定子铁芯与定子屏蔽构件的装配过程进行了研究。首先提出了5种不同内压加载路径的装配过程，通过分析成形能力确定了较为合适的加载路径；接着在此加载路径基础上分析了成形能力与内压力关系随初始间隙变化的规律；最后分析了不同摩擦因数对装配过程的影响。研究表明：数值模拟法有助于装配方案的确定以及装配效果的预测；装配中存在一定的摩擦可获得到较好的装配效果。

Numerical simulations were conducted to study the hydro forming assembly of the AP1000 stator components .Firstly ,five different loading paths were suggested to study the assembly effects .A suitable loading path was obtained based on the analyses of the formability .Then the rela-tionships between the bulge ability and the internal pressure with the change of the initial clearance were analyzed .Finally ,the effects of the coefficient of friction on the assembly process were examined . The results show that the simulation method benefits the determination of assembly process and the prediction of assembly effects ,and a better assembly result can be obtained by a proper coefficient of f rictio n .
