摘　　要：介绍了基于ANSYS的结构优化设计的基本原理和方法,在满足给定的刚度和强度的要求下使得压力容器的重量最小,并建立压力容器重量最小时的数学模型;利用大型有限元分析软件ANSYS10.0对该压力容器采用自由网格法建立该压力容器有限元模型,对壁厚进行优化分析,得到了合理的结构形式和尺寸。最后对优化前后的压力容器重量进行比较,发现优化后的压力容器重量下降了大约8%,从而可以节省大量工程材料。The paper has introduced basic theory and method of structure optimization design based on ANSYS, and established the smallest weight ＇s mathematical model of the pressure vessel, which meets the request of rigidity and intensity. Then use the large scale finite element software ANSYS10. 0 to established the pressure vessels finite element model with the method of free meshing, optimized analysis the wall thickness of pressure vessel, and obtained the reasonable structure form and size. In the end, comparing the optimized pressure vessel weight with non-optimized one, it is showed that the optimized weight decreases about 8% , so it can save a lot of engineering materials.
