水下冲击波作用下结构损伤的数值预报误差分析
Error Analysis of Numerical Prediction of Structure Damages Subjected to Underwater Shock
摘要
Abstract
Considering the absence of hull vibration damping data from prototype experiment, the method of distribution of test points and identification was studied based on the experimental data of hull general vibration. The conceptions of Resonance Response of Nature Mode and Neighboring Vibration Response of Nature Mode were introduced. The law of ratio in Neighboring Vibration Response of Nature Mode, Non-resonance Response of Nature Mode and Resonance Response of Nature Mode was analyzed. According to the law, the total vibration test conditions of a sailing ship were implemented, and the bending hull vibration damping data were obtained.关键词
