摘要
应用ANSYS软件优化模块,以自重最轻为目标函数,以强度、稳定性等为约束条件,并考虑了结构几何非线性的影响,对凯威特型单层球面网壳进行优化分析。然后对优化所得的网壳作了稳定性全过程分析,从而验证优化设计是可靠的。
A structural optimization algorithm is performed for single-layer Kiewit reticulated dome by means of ANASYS. In the process of optimum design, the overall weight is taken as objective function; the stress constraints and stability constraints etc are considered. Meanwhile, the geometrical non-linearity is taken into account. Then the overall stability analysis for the optimized single-layer reticulated dome is operated. The results show that the optimization design is reliable.
