| 摘 要： | 对未来聚变工程实验堆真空室1/8段预研计划中第一个1/32扇区的焊接过程进行了分析。数值模拟采用固有应变法,比较并设计了1/32段扇区的焊接工装,同时对焊接形变趋势和形变量进行了预测。焊接过程中控制点的偏移反映了1/32段扇区整体的形变趋势和形变量与数值模拟结果相符合,焊接工装的设计与焊接过程中预补偿的应用有助于提高1/32段的制造精度。

| Abstract: | The welding process of the first 1/32 sector in the 1/8 section research and development project of the future fusion engineering test reactor vacuum vessel (VV) was analyzed. In the numerical simulation, the inherent strain method was used to compare and design the welding tools for 1/32 sector. Meanwhile, the trend of welding deformation and the amount of deformation were predicted by the simulation model. The displacements of the control points in the welding process are consistent with the numerical simulation results. The design of the welding tools and the application of the pre-compensation in the welding process are effective in improving manufacturing accuracy of the 1/32 VV sector. |
