摘要
三体船连接桥部位应力集中严重,疲劳强度问题突出。针对三体船结构疲劳强度问题,从工况确定、载荷计算、累计损伤推导等方面进行研究,提出一种适用于三体船结构疲劳分析的简化方法,并以某三体船为例进行算例分析。算例分析结果表明该方法具有很好的适用性。文中所得结论对三体船的研发设计具有参考意义。
The stress concentration of trimaran ship＇s cross-deck structure is serious and the problem of its fatigue strength appears particularly important. According to the problems of trimaran＇ s structure fatigue strength,the simplified method for the trimaran＇s fatigue strength evaluation is studies from the load case decision,load calculation,and the accumulative damage calculation. And one trimaran is chosen as example for studying the simplified method of fatigue strength evaluation. The example analysis results shows that the method given in this paper has a good applicability. The conclusion reached in this paper can offer the reference for the trimaran＇s design and development.
