| 摘 要： | 基于IGF规则对LNG燃料船储气罐疲劳强度分析的相关要求,结合CCS相关规范指南中的拟合经验公式,对船用储气罐的疲劳强度评估方法进行了研究,推导了累积损伤计算的简化公式并通过算例同CCS《船体结构疲劳强度指南》中的经验公式进行了简单对比。结果表明,简化公式可有效的对疲劳累积损伤度进行计算。

| Abstract: | Study of fatigue strength for the tank of LNG-fuelled ships is carried out based on the International Code of Safety for Gas-fuelled Ships (IGF Code). Some empirical formulas of the Guidelines for Assessment of Ship Structure Fatigue Strength (CCS) are used to derive a simplified formula for the calculation of the cumulative damage. To demonstrate the effective of the method, a comparative analysis is carried out with respect to the method offered by the Guidelines of CCS. |
