1500m^3立式圆筒形煤仓有限元计算

Finite Element Calculation of 1500m^3 Vertical Cylindrical Bunker

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 1 500 m3 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.
