| 摘 要： | 本文针对结构应力监测系统的疲劳监测点选取问题,根据规范初步筛选出疲劳危险点,利用谱分析法和应力集中系数法计算各类危险点的损伤度。基于各危险点损伤和坐标,设计了考虑损伤度和位置的程序进行筛选,进而确定疲劳监测点的位置。最后针对某艘船,运用上述方法确定了疲劳监测点的位置。

| Abstract: | Focused on the arrangement of the fatigue monitoring point, the fatigue hotspot is selected initially according to the related regulations. Then the spectral analysis method and the method based on stress concentration factor are applied to calculate the damage of the fatigue hotspot. Then according to the location and the damage of selected points above, the designed program are adopted to determine the layout plan of the fatigue monitoring point on the hull. Finally, take a ship as an example. The layout plan of the fatigue monitoring point is given in the method described above. |
