江海通航船货舱结构强度有限元分析

针对某江海通航船的货舱结构建立有限元模型,利用APDL语言实现波浪载荷的自动施加。分析江海通航货船在满载出港和压载到港两种典型工况下货舱结构的应力水平,并将有限元分析结果同传统的梁理论分析结果进行比较。

Structure strength finite element analysis of cargo tank for river-sea-through ships

According to river-sea-through prototype,ANSYS finite model of cargo compartment was build.With the wave load applied by APDL program,the stress of the cargo compartment structure in two typical conditions which are full load and ballast are analyzed.At the same time,the results of Finite Element analysis and classical beam theories analysis are compared.Some beneficial conclusions and necessary design basis in static strength of cargo compartment structure for river-sea-through ships are obtained.
