中文摘要：

为了准确估算船体面板滚弯成形作业时间,通过分析在滚弯过程中船体面板的弹塑性变化和滚弯成形后的最终状态,建立了滚弯成形最终状态下船体面板滚弯成形作业时间估算模型.与实测数据对比分析结果表明,基于弹塑性变形理论的总进给距离与实测进给距离无显著性差异,通过作业时间估算模型得出的理论作业时间与实测作业时间也无显著性差异而且相对误差都在10%以内（平均相对误差为5%）.因此,基于弹塑性变形理论的船体面板滚弯成形作业时间估算模型合理且符合作业实际状况.

英文摘要：

In order to estimate the hull panel roll bending processing time accurately,first,both the panel’s elastic and plastic deformations in the hull panel roll bending processing were analyzed along with the final state after roll bending processing.Then,a model of hull panel processing time was developed.The model was further evaluated by comparing its estimated processing time for different hull panels with the practically measured data.The results show no significant difference between the top roll positions calculated based on elastic and plastic deformation theory and the actual positions.There was no significant difference in processing time between the estimation from the proposed model and the actual measured processing time;all estimated errors were within 10%（the average error was 5%）.Therefore,the proposed estimation model of ship plate processing time based on elastic and plastic deformation theory is reasonable and feasible for real practice.
