摘要：

The operating procedure of frame twisting process is investigated. The distributions of the heat input parameters are identified by performing spot hearing test. The temperature histories in a T-shape ship longitudinal frame during face and web heating processes are estimated using the identified heat input parameters. The relationship between the residual and constrained deformation is calculated by elastic-plastic FE analysis using the estimated plate temperature as thermal body force. The calculated deformation agrees approximately with the measured one. This shows the accuracy and validity of the employed techniques for plate temperature and frame deformation estimation. It is also shown that substantial reductions in computing costs can be achieved without loss of accuracy by performing shell-based FE analysis.
