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。
採用非線性有限法進行艦船極限彊度計算,併結閤勞氏軍規中關于極限彊度的要求進行極限彊度評估。依據極限彊度評估結果,確定模型試驗的研究對象,基于非線性有限元計算和模型試驗結果進行實船極限彊度預報,形成一套非線性有限元法和模型試驗相結閤的實船極限彊度預報方法,為艦船的極限彊度計算和試驗提供參攷。

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.
