Taking austenitic stainless-steel bellows as the research object, a finite element model for the heat treatment of austenitic stainless-steel bellows was constructed based on ABAQUS CAE 2022. The physical properties of the bellows after the heat treatment were analyzed using experimental and simulated curve processing analysis methods. The changes in residual stress and deformation in relation to the bellows under different cooling times were explored, as well as the distribution of residual stress and deformation at a certain cooling time. The results show that as the cooling time of the heat treatment increases, the residual stress of the bellow decreases significantly, the reduction rate accelerates, and the degree of deformation gradually decreases. When the cooling time of the heat treatment is 900 s, the residual stress of the wave peak in the middle position of the bellow is relatively small, and the residual stress value of the wave valley along the axis direction does not change significantly. The deformation degree of the wave peak and valley axis direction is relatively uniform.
以奥氏体不锈钢波纹管为研究对象，基于ABAQUS CAE 2022构建了奥氏体不锈钢波纹管热处理的有限元模型。采用实验和模拟曲线处理分析方法，分析了热处理后波纹管的物理性能。探讨了不同冷却时间下波纹管残余应力和变形的变化情况，以及某一冷却时间下残余应力和变形的分布情况。结果表明，随着热处理冷却时间的增加，波纹管的残余应力显著降低，降低速率加快，变形程度逐渐减小。当热处理冷却时间为900 s时，波纹管中间位置波峰处的残余应力相对较小，沿轴线方向波谷处的残余应力值变化不明显。波峰和波谷轴线方向的变形程度相对均匀。
