摘　　要：以某钢制立式圆筒形空气储罐的设计为例,对比了焊接H型钢和钢管用作设备支腿的性能差异。在载荷和网格划分相同的情况下,分别采用焊接H型钢和钢管作为支腿材料,对设计变量、约束条件和目标函数进行设置。运用SolidWorks Simulation数值模拟软件,对初选的WH300 mm×200 mm×10 mm×16 mm焊接H型钢和Ф273 mm×10 mm钢管支撑结构进行静应力分析及优化设计分析,得到2种方案下满足设计要求的支腿为WH200 mm×200 mm×4 mm×6 mm焊接H型钢和Ф108 mm×7 mm钢管。在满足支撑结构要求并且安全可靠的情况下,采用WH200 mm×200 mm×4 mm×6 mm焊接H型钢制作的支腿质量比采用Ф108 mm×7 mm钢管的多29.35%,采用Ф108 mm×7mm钢管更优。Taking the design of a steel vertical cylindrical air storage tank as an example,the performance difference between welded H-shaped steel and steel pipes used as equipment legs was compared.In the case of the same load and mesh division,welded H-section steel and steel pipe were used as outrigger materials,and the design variables,constraint conditions,and objective functions were set.By using SolidWorks Simulation numerical simulation software,the preliminary selected WH300 mm×200 mm×10 mm×16 mm welded H-shaped steel andФ273 mm×10 mm steel pipe supporting structure were analyzed for static stress and optimized design,and the design was satisfied under the two schemes.The required legs are WH200 mm×200 mm×4 mm×6 mm welded H-shaped steel andФ108 mm×7 mm steel pipe.Under the condition of meeting the requirements of the supporting structure and being safe and reliable,the mass of outriggers made of WH200 mm×200 mm×4 mm×6 mm welded H-shaped steel is 29.35%higher than that ofФ108 mm×7 mm steel pipe,andФ108 mm×7 mm steel pipe is better.
