某电厂设计中为满足工艺要求,采用了椭圆形钢煤斗方案,但因其空间曲面构形复杂,利用现有国家规范将难以设计.本文结合该工程实例利用有限元分析软件ANSYS计算分析了全部满煤和半边满煤半边放空两种工况下煤斗的应力和应变分布规律,进而给出了最大应力和最大位移的具体部位,为煤斗的施工图设计提供了重要的依据. In order to meet the technical requirements of a power plant, an oval steel coal hopper solution is adopted, but because of its complicated curved surface shape, it is difficult to design using the existing national codes.This paper combines the project example with the finite element analysis software ANSYS All coal and half full of coal and half full of coal emptying under two conditions of the coal bucket stress and strain distribution, and then gives the maximum stress and maximum displacement of the specific parts of the coal bucket for the construction design provides an important basis.
