大型塔器整体吊装吊耳有限元分析

Finite Element Analysis of Lifting Lugs for Integral Lifting on Large Tower Vessels

随着现代制造技术水平的提高,塔器设备日趋大型化,复杂化,重型化。吊耳作为塔器关键部件之一,在吊装作业中起着举足轻重的地位。吊装过程的安全与否,源自于吊耳结构设计的合理性和强度校核的准确性。文章以丁烯塔为例,采用壳单元,梁单元以及实体单元组合单元类型,对吊装过程中轴耳,尾耳及其连接局部区域的受力进行有限元分析,旨在为塔器吊耳的计算提供一种有益参考。

With the advancement of modern manufacturing technology,tower equipment has become increasingly large-scale,complex,and heavy.The lifting lug,as a key component of tower vessels,holds a critical position in lifting operations.The safety of these operations fundamentally depends on the rationality of the lifting lug's structural design and the accuracy of its strength verification.This paper,taking the Butene Tower as an example,adopts a combination of shell elements,beam elements,and solid elements to perform a finite element analysis on the force distribution across the trunnion,tail lug,and their interconnected local regions during the lifting process.The aim is to provide a useful reference for the calculation of tower lifting lugs.
