摘要
收发油作业时液面的升降对浮顶有一个冲击载荷,可能引起浮顶变形.为研究浮顶在收发油冲击载荷作用下的力学响应情况,采用多物理场耦合软件,建立了浮顶固体模型与油品的液体模型.考虑液面晃动的影响,分析了不同液位高度和不同收发油速度下对浮顶稳定性的影响.结果表明:收发油冲击载荷对浮顶的影响集中在距离收发油孔1～6 m的浮顶范围,随着收发油稳定,冲击载荷明显减小,收发油过程对浮顶的稳定性影响较小.
Abstract
The rise and fall of the liquid during the oil receiving and sending operation have an impact load on the floating roof,which may cause deformation of the floating roof.To study the mechanical response of the floating roof under the impact load of receiving and sending oil,the multi physical field coupling software was used to establish the solid model of the floating roof and the liquid model of the oil based on the basic parameters of the floating roof and the oil.Considering the influence of liquid level sloshing,the influence of different liquid level heights and oil receiving and sending speeds on the stability of floating roof was analyzed.The results showed that the impact load of receiving and sending oil on the floating roof was concentrated in the range of 1 m to 6 m from the oil receiving and sending holes.With the stability of receiving and sending oil,the impact load was significantly reduced,and the impact of receiving and sending oil on the stability of the floating roof was small.
