【摘要】 本文以ANSYS软件为基础,对高压长圆柱形天然气储运罐进行变形分析、应力分析,得到了储气罐的应力分布状态,分析了在壁厚方向及沿着罐壁方向上的应力变化。所得结果和理论结果吻合。此基础上,完成了气罐模态分析,得到了气罐的各阶固有频率及振型。计算结果表明计算方法有效,为进一步设计高压气罐提供了理论依据。更多还原

【Abstract】 In this paper,based on Ansys the deformation and stress for high pressure long cylindrical natural gas storage tank are analysed.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 theoretical basis for high pressure tank design.更多还原
