多用途拖船尾滚筒结构强度计算及研究

Study and calculation of structural strength of the stern roller of supply tug

该文采用有限元方法对某型多用途拖船尾滚筒的结构强度及稳定性进行了分析及计算,尝试利用了积分加载的方式施加结构的外载荷,分两种不同的工况对结构的主要参数进行了具体分析和比较,计算结果及经验分析验证了该外载荷施加方式的正确性,为尾滚筒的结构强度设计及稳定性分析工作提供了一定的参考。

This paper analyzes and calculates the structural strength and stability of the stern roller of the supply tug with finite element method, attempts to employ the integral load method to put external load on structure, analyzes and compares the main parameters under two different operating conditions. The calculation result and experienced analysis has validated the external loading mode to be correct, and can be reference to the structural strength design and stability analysis of stern roller.
