Abstract

In this paper, we examine the possible usage of compressive sampling (CS) for the efficient measurement and analysis of floating breakwaters dynamics. We model the dynamics of a box-type floating breakwater in a random sea environment with the Bretschneider-Mitsuyasu spectrum. The spectral method involving FFT and IFFT routines is used for the simulation and CS reconstruction purposes of the displacement and velocity parameters. The time series of forces are calculated using the Morison equation. It is also shown that those vibration parameters can be limited and suppressed to a certain degree by a tuned-mass-damper. The advantages of using the CS for the tuned-mass-damper-controlled vibration parameter measurement and analysis are also discussed. Our findings may provide convenience for the effective and efficient strategies for the vibration-induced problems of floating platforms including wave energy converters and offshore platforms.
基于压缩感知的浮式防波堤振动有效测量及振动参数控制
在本文中,我们研究了压缩采样(CS)在浮式防波堤动力学的有效测量和分析中的可能应用。我们用Bretschneider-Mitsuyasu谱对随机海洋环境下箱式浮动防波堤的动力学进行了建模。采用涉及FFT和IFFT例程的谱法对位移和速度参数进行模拟和CS重建。力的时间序列是用莫里森方程计算的。研究还表明,调谐质量阻尼器可以在一定程度上限制和抑制这些振动参数。讨论了CS用于调谐质量阻尼器控制振动参数测量和分析的优点。本研究结果可为波浪能转换器和海上平台等浮动平台振动诱发问题的有效解决提供便利。
