In this paper, The finite element structure of the unloading arm is calculated and analyzed for the first time, and some design optimization suggestion is given. There is a large stress concentration at the joint of the three-dimensional joint and the pipe of the outer arm, the structural design process should be paid attention to. The structural strength of the lengthening position of the support box is weak, a pipe with thicker wall should be used. Aiming at the emergency release system of the key core components of the unloading arm, an innovative hoop locking mechanism is designed based on the principle of mechanical dead point, and finite element calculation and performance test results show that the stress and deformation of the hoop locking device meet the design requirements, and that its stability and reliability also meet the needs of the unloading arm operation, thus providing a reference for safe and reliable operation of large LNG unloading arm., authors=YANG Liang, XIAO Li, XU Jiawei, HAO Sijia, QIU Zaoyang, FAN

articleAbstract=液化天然气卸料臂是连接运输船与接收站管线，输送液化天然气（LNG）的重要通道。针对卸料臂开展了有限元结构计算分析并给出设计优化建议。三维接头和外臂管道连接处存在较大的应力集中，结构设计过程应予以关注；支撑箱加长位置结构强度偏弱，应采用壁厚较厚的管材制造。针对卸料臂关键核心部件紧急脱离装置，基于机械死点原理创新设计了抱箍锁紧机构，并开展有限元计算和性能试验测试，结果表明，抱箍锁紧装置的应力和变形量符合设计要求，稳定可靠性满足卸料臂作业需要。,
