摘要

低温管道系统结构复杂

在工作时承受内压、温差及重力载荷

且承载时系统内各部件又相互影响和制约

采用传统材料力学或结构力学很难分析该系统内各部件应力情况。应用ANSYS软件对某液化天然气储罐的顶部进液管进行了结构强度分析

分析得到了顶部进液管在承受内压、自身重力以及温差应力作用下的变形和应力分布情况

基于此对进液管的布置进行结构调整。研究结果表明:优化设计后进液管道最大主应力小于原设计进液管最大主应力的1/6

极大地保证了储罐在使用过程中的安全性。

Abstract

Cryogenic pipeline system structure is complex

it endures internal pressure

temperature and gravity loads while working.Besides

the components in the system are under mutual influence and restriction.So it's hard to analysis the stress of different parts in the system with the method of the traditional mechanics of materials and structural mechanics.ANSYS software is used to analysis the structural strength of the top inlet pipe for the LNG storage tank.The deformation and the stress of the top inlet pipe enduing pressure

gravity and temperature stress are got.Based on this

the arrangement of the top inlet pipe is adjust.The result of the research shows that:The maximum principal stress of the optimized design of the top inlet pipe is less than that of the original design of the maximum principal stress of the top inlet pipe 1/6

which greatly ensure the safety of storage tank in use process.
