摘要
用有限元数值方法,对某液化气船的一个C型双联圆筒形液罐进行了应力分析,建立了液罐内部液体压力(静态和动态)的算法,开发了相应的计算程序。最后给出一个典型液罐应力分析的主要结果,并按规范要求做了强度校核。
In this paper the FEM is adopted to complete the stress analysis of C-type bi - cylinderical vessel for LPG tanker. The calculation algorithm of inner liquid pressure (static and dynamic) on the vessel is established and the corresponding computer program is developed. At last,the main analytical results of a typical liquid gas vessel are given and strength check was made according to DnV rules.
