【摘要】 针对当前缺少来自于实船试验的总振动阻尼数据的现状,研究一种基于实船航行振动试验数据进行总振动阻尼研究的测点布置和识别计算方法。清晰表述了"模态共振响应"和"模态相邻振动响应"的概念;分析了"模态相邻振动响应"、"模态非共振响应"和"模态共振响应"三者的比例规律,按该规律指导制定了某船航行总振动测试工况,使用该船航行总振动测试数据获得了该船的弯曲总振动阻尼数据。更多还原

【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.更多还原
