曲がりブロック溶接変形の推定法

Precision of a ship building block gives large influence on a number of works to load the block into a dockyard. So many research projects have been carried out, and measurements of weld deformation and investigations to estimate weld shrinkage have been promoted. However, the methods applicable to a curved block that has curved shell plates were limited.
In this paper, the calculation methods on weld deformation are reviewed, and a new method applicable to the curved block is proposed. The results of experiments, in which weld deformations were measured in two models, are compared with the calculated values using the proposed method. Both experimental and calculated values are in good agreement, and the availability of the method is confirmed.
