Numerical Analysis of Ring Beam Effect on the Modal of LNG Storage Tank

Abstract:

LNG storage tank is an important department in the gas receiving station. LNG in the tank is flammable and explosive medium, once the tank damaged, disasters may be happened. So researching the dynamic response analysis is very necessary. In this paper, modal analysis of LNG outside tank were performed by ANSYS Workbench, the first six orders of mode shapes and their frequencies of LNG outside tank were concluded. Contrast vibration mode and natural frequency of the LNG storage tanks with ring beam and no ring beam, the influence of ring beam of LNG tank mode has been discussed. Conduct a series experiment by change the parameters of the ring beam, Parameters for ring beam effect on the inherent frequency and vibration mode of LNG outside tank has been researched. This research has provided the provided the reliable basis for the safety using of tanks and has built the base of the further dynamic response analysis.
