摘要
针对某4 000 t三体船,采用谱分析方法和《英国劳氏三体船规范》法两种方法分别对其典型节点进行疲劳强度评估,对得到的疲劳寿命进行探讨,并对计算结果差异性进行分析,研究结果可为其他船型的疲劳强度评估提供参考。
Focusing on a trimaran of 4000t, the fatigue strength of its typical spots is evaluated by two ways of the spectral analysis and the rule method. The calculation results of the fatigue life of two methods are discussed. The difference between the two methods ＇results is analyzed. The result of the study provides reference for the fatigue strength evaluation of other ship types.
