In this paper, based on Ansys the deformation and stress for high pressure long cylindrical natural gas storage tank are anal- ysed. And obtain the stress distribution of the storage tank. The changes of stress are analysed in thickness direction and along the rigid wall. The results and theoretical results are accordance. On this basis, the modal analysis of tank is completed too. Obtained the tank various order natural frequency and vibration mode. The calculation results show that the method is effective and provide the theoreti- cal basis for high pressure tank design.
