舰船结构极限强度计算及试验研究

摘要

采用非线性有限法进行舰船极限强度计算，并结合劳氏军规中关于极限强度的要求进行极限强度评估。依据极限强度评估结果，确定模型试验的研究对象，基于非线性有限元计算和模型试验结果进行实船极限强度预报，形成一套非线性有限元法和模型试验相结合的实船极限强度预报方法，为舰船的极限强度计算和试验提供参考。%Ultimate strength of a warship is calculated by non-linear FEM and is evaluated according to the requirements of Lloyd’s Rules and Regulations for the Classification of Naval Ships. It determines the study subject for the model test based on the evaluation, and forecasts the real ship ultimate strength based on the calculation from the nonlinear FEM and model test results. It finally forms a method to predict the real ship ultimate strength by the combination of nonlinear FEM and model test, which can provide reference for the calculation and test of the ultimate strength of warships.
