非标准矩形截面容器的应力分析和数值计算

Stress Analysis and Numerical Computation of Pressure Vessel with Nonstandard Rectangular Cross Section

具有四块拉撑板的矩形截面容器的应力计算,GB 150—1998不适用。针对其特殊结构,进行了受力分析,推导出理论计算公式,并将计算结果与有限元分析结果进行对比,结果表明,理论解与数值解吻合较好,从而为工程设计提供了可参照的方法。

The stress calculation formulas of rectangular cross section pressure vessel with four pieces of bracing plates are not suitable to the standard GB 150-1998. The paper performs stress analyses according to its special structure, derives theoretical calculation formulas and compares the result of calculation with that of finite element analysis, the result shows that the theoretical value is the same as the numerical value, thus providing engineering designs with referential methods.
