摘　　要：采用有限元仿真通用平台Abaqus模拟了核反应堆中不锈钢管接头淬火过程,分析了淬火后残余应力的分布情况,得到了残余应力在管接头内外表面的分布特性。研究了改变淬火温度与淬火冷却速率对残余应力分布特性的影响,然后结合不同淬火工艺实现的条件,在保证最低资源消耗与得到最佳残余应力场的情况下,寻求最优的淬火工艺条件,为企业的淬火工艺制定提供了一种很好的参考。The FEM software of abaqus is used to simulate quenched residual stress of stainless steel tube connector and distribution of residual stress in the axle deep below the surface and the layer is obtained. The effect of quenching temperature and quenching cooling rate on residual stress distribution characteristics is researched, and then combined to achieve different quenching conditions, the guaranteed minimum consumption of resources and the best case of residual stress field and find the optimal quenching conditions quenching process for enterprise development provides a good reference.
