摘要
设计了一种船用球形压力储气罐,应用软件Ansys进行了有限元建模,根据有限元模型的应力分析情况,选取三个危险截面仔细做应力分析,并进行结果评定。最后运用Ansys载荷步分析方法获得交变应力强度,分析了储气罐的疲劳性质。
One kind of spherical pressure gas tank for ship & designed The finite element model is buifl by software Ansys. According to the stress distribution in the finite element model, three dangerous sections are selected and analyzed carefully, and the results are evaluated Finally, the alternating stress intensity is obtained by using a load step analysis method of software Ansys. and the fatigue property of the gas tank is analyzed.
