单舷侧散货船肋骨上下端的支撑结构比较分析

Comparison Analysis on Structure of the Lower and Upper End Connections of Side Frames

对于单舷侧散货船肋骨上下端支撑肘板是否采用延伸结构形式的问题,采用有限元方法进行计算分析,比较应力计算结果,检验肋骨上下端肘板支撑结构的有效性。结果表明,肘板末端添加延伸结构无益于肘板处的应力水平。

The FEA direct calculation method was used to evaluate the effectiveness of the extending structure of the lower and upper end connections of side frames for the single side bulk carriers. By comparative analysis of the numerical results of stress distribution, it proved that the efficient support is just the bracket between longitudinals adjacent to the side frame, and the extending structure from the bracket is useless for decrease the stress level on the bracket.
