浮式结构物附加重量与附加阻尼的仿真和识别

浮式结构物可以简化为由弹簧-质量-阻尼组成的模型。首先，使用数字滤波器对其简化出模型进行仿真。其次，在简化模型的基础上对浮式结构物垂荡方向的附加重量和附加阻尼进行识别。最后，为验证该方法的正确性，以一个漂浮的垂直圆柱体为例子，进行计算分析。分别对实际的附加重量和附加阻尼与识别得到的附加重量和附加阻尼进行比较，结果显示吻合性较好，从而证明了本文所提出的方法的正确性。

Simulation and identification of added mass and added damping for

In this paper, the marine structure is simplified into a spring-mass-damping system. Firstly, digital filters are used to simulate the system. Secondly, identification of added mass and damping coefficients for heave mode of a hydrodynamic structure are computed. To verify the result, a simple example is illustrated. Comparing true added mass and added damping with identified added mass and added damping respectively, which shows they are in good agreement, and it implies that the present method is correct.
