Abstract

The LNG unloading arm is one of the important equipment of LNG storage and transportation, whose performance directly affects the efficiency and safety of LNG handling. In this paper, the 16-inch unloading arm is taken as an example to carry out weight reduction optimization for the supporting structure of the unloading arm, such as the column and the inner and outer walls, and the finite element simulation analysis is carried out on the weight reduction unloading arm under working condition. Through the numerical simulation method, the thermal solid coupling check analysis, vibration analysis, and buckling analysis of the column are carried out to fully check the weight reduction unloading arm. The results show that the strength of the weight reduction unloading arm meets the requirements and has good vibration characteristics and stability. At the same time, the total weight of the device is reduced, and the processing and manufacturing costs are saved, which has guiding significance for the production and manufacturing of LNG unloading arm in practical engineering.
