摘　　要：船体结构庞大而复杂,船体总纵强度的模型试验十分困难,因此船体梁模型的简化方法对船体结构的总纵强度研究具有重要意义。本文针对船体梁失效模式,提出船体梁模型的简化方法。根据该简化方法建立中垂及中拱工况下船中舱段的简化模型,比较完整模型与简化模型的极限弯矩,验证该简化方法对于分析船体梁极限弯矩的可行性,为船体梁极限强度和剩余强度的研究提供参考。The model test of hull longitudinal strength is very difficult because of huge and complex hull structure.Therefore,simplified method of hull girder model is of great significance to the study of hull longitudinal strength.Aiming at the failure mode of hull girder,a simplified method of hull girder model is proposed in this paper.According to the simplified method,a simplified model of mid-hull section under hogging and sagging condition is established.The ultimate bending moment of the complete and simplified model is compared to verify the feasibility of this method for analyzing the ultimate bending moment of hull girder.The method provides a reference for the research of ultimate strength and residual strength.
