球罐地震反应分析及其子结构拟动力试验方法

为了研究流固耦合作用对球罐地震反应的影响,利用ABAQUS软件建立1 000m3球罐有限元模型。采用子空间法对球罐进行了模态分析,并与规范算法进行对比,同时采用耦合拉格朗日欧拉算法,对考虑液固耦合作用的球罐进行地震反应分析。分析结果表明:考虑液固耦合作用使球形储罐的顶点位移、竖向支反力、支柱底部剪力以及拉杆应力等方面衰减得更快,并且在数值上也比附加质量法所模拟的结果小很多。在此基础上,介绍了子结构拟动力试验方法,提出将子结构拟动力试验方法应用于球形储罐的抗震性能分析,阐述了球形储罐子结构拟动力试验的步骤,为球形储罐抗震研究提供一种新的试验研究思路。

Hydrochloric acid tank explosion

Explosions in hydrogen chloride storage tanks are very rare. However, we have experienced one. The explosion was so powerful that the tank with a capacity 250 kL, 60% filled with 33% HCL, took off from the ground went up to 8–9 m high in air and landed around 50 m away. The contents of the tank sprayed all over the nearby area. Though the tank was surrounded by other plants and equipment, fortunately, it landed in a barren area. This averted loss of life and property that would have otherwise resulted. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009
