某型航行横向补给系统干货发送柱结构强度有限元分析
|
摘要
某型航行横向补给系统主要用于加装在民用船舶上,其主要承力部件干货发送柱设计为组合式结构,并仅通过螺栓联结在甲板预设的安装底座上。针对发送柱的受力分析与计算要求,采用MSC/Patran软件建立发送柱的有限元模型,通过分析正常作业工况、自动解脱工况下的外力状况,以及发送柱底端固定、顶端受力和重力等边界条件,在软件中对模型施加相应载荷并得到应力和变形结果。采用MSC/Nastran的SOL106求解器对模型进行非线性静力计算,计算结果证明发送柱的结构强度设计满足要求。
A new type replenishment equipment is used for civil container ships equipping,the main bearing component-the delivery column is connected with the mounting base on the deck through bolts. Aiming at the structure strength analysis of the highline bearing column,established the finite element simulation model by MSC/Patran. By analyzing the external force conditions under normal working conditions and automatic relief operation,and the boundary conditions of the bottom end of the column,the top force and gravity,the corresponding loads were applied to the model and the stress and deformation results were obtained. Nonlinear static calculation of the model was carried out by using the SOL106 MSC/Nastran solver. The results show that the structure strength of the column designation meets the requirements of specification,and the performance tests of the device prototype are carried out to verify the designation.
