摘要
大型圆筒式煤仓在油田燃煤注汽站工程中应用广泛,对某1 500m3立式圆筒形煤仓进行了应力强度分析。运用有限元软件ANSYS建立了与煤仓罐顶、罐壁、支座连接、锥底、支撑钢架以及立柱实际尺寸相一致的有限元数值计算模型,利用软件的边界模拟和各种荷载施加功能,针对煤仓各结构部分,在充水状态+风载荷+雪载荷+地震载荷工况下进行了应力计算和校核,结果表明,此煤仓具有足够的安全裕度及可靠性。
Large cylindrical bunker is widely used in oil fired steam injection station project.An analysis of stress strength for the design of a 1 500m3 vertical cylindrical bunker is given.A large general finite element software ANSYS is used to establish a actual size of the finite element numerical model,which connected with a coal bunker tank top,tank walls,bearing,cone bottom,consistent with steel support columns,using powerful border simulation and all kinds of applied load function,in a state filled with water+ wind + snow +load cases,to calculate and check the various structural parts of coal bunker.The calculated results show that it has sufficient safety margin and reliability.
