| 中文摘要: |
| 损耗因子是衡量系统阻尼特性并决定其振动能量耗散能力的重要参数，对船舶水下噪声预报分析具有重要影响。针对船舶结构特点，选取内底板、舱壁板和甲板等典型结构建立试验模型，基于瞬态衰减法，对船舶典型结构损耗因子进行测试，分析、掌握其特性规律。在此基础上，开展船舶典型结构损耗因子水下噪声预报应用研究，结果表明，损耗因子对船舶水下噪声具有较大影响，进行船舶水下噪声预报时需开展相关损耗因子测试。 |
| 英文摘要: |
| Loss factor is an important parameter to measure the damping characteristics and determine its vibration energy dissipation capacity of a system. It has an important influence on underwater noise prediction and analysis of ships. According to the characteristics of ship structure, select the ship typical structures of hull plate, side plate and hull deck as the test model, test the typical ship structure loss factor in the method of transient decay, analysis of loss factor characteristics of ship typical structure. Based on all above, carry out the research on the application of loss factor test results in ship underwater noise prediction. The results show that the loss factor has a great influence on ship underwater noise, and it is necessary to carry out basic parameter test for ship underwater noise prediction. |
