【摘要】：由于海洋平台结构长期处于恶劣的海洋环境中,并受到各种载荷的交互作用,结构容易产生各种形式的损伤。因此,对海洋平台进行实时监测有着十分重要的现实意义。以单筒简易导管架平台为例,主要在结构损伤的判定和定位两方面对海洋平台的实时结构健康监测进行研究,结果表明通过对结构响应信号进行小波分析,小波变换系数和小波包能量分布可以很好地定义损伤识别指标。
[Abstract]:Because the offshore platform structure is in the bad marine environment for a long time and is subjected to the interaction of various loads, the structure is prone to various forms of damage. Therefore, real-time monitoring of offshore platforms is of great practical significance. Taking a simple jacket platform as an example, the real-time structural health monitoring of offshore platform is studied in two aspects of structural damage determination and location. The results show that the wavelet analysis of structural response signal is carried out. Wavelet transform coefficient and wavelet packet energy distribution can define damage identification index well.
