摘要
针对薄壁板壳结构的特点,建立数学优化模型和有限元模型,以某试验舱为例,采用有限元计算方法和序列二次规划法迭代优化算法,有效地实现了结构优化目标——小质量和大强度/刚度。
Aiming at characteristic of the thin-walled structure, the mathematic optimizing model and FEM model is constructed. An example of testing cabin is optimized by FEM and SQP, achieving effectively structural high strength, high stiffness and light mass.
