摘要
基于SYSWELD软件对钢制安全壳筒体环建立了有限元模型,对拟定的筒体纵焊缝热处理工艺采用有限元法进行了模拟分析,计算了热处理后的畸变和残余应力,并将数值模拟分析的畸变数据与实测数据进行了对比,证明了拟定的工艺满足产品技术要求,可为超大型容器局部焊后热处理提供参考。
Based on the SYSWELD software,a finite element model was established for the cylinder ring of steel containment vessel.The heat treatment process of longitudinal weld of the cylinder was simulated by finite element method.The distortion and residual stress after heat treatment were calculated.The distortion data of numerical simulation analysis were compared with the measured data.It is proved that the proposed process meets the technical requirements of the product and can provide reference for local post-welding heat treatment of super large vessels.
