摘要
对于受外压的容器,除了圆筒、球壳、锥壳和有限定的开孔外,其他的很多形状以及不均匀的载荷等都无法按照现有的标准规范进行稳定性校核。通过分析结果的对比,确定了基于有限元屈曲分析为基础的压力容器稳定性分析方法和评判准则。
In addition to cylindrical shell, spherical shell, conical shell and certain nozzle openings subjected to external pressure, the stability analysis for many other shells of special shape or under non-uniform load subjected to external pressure could not be carried out in accordance with the existing Standards and Codes. This paper proposes a stability analysis method and evaluation criterion based on the buckling analysis by finite element method, which may be applicable to the pressure vessel of any shape or under non-uniform load.
