摘要
本文建立了壳体结构优化的序列二次规划模型,对八节点等参壳单元做了优化处理,扩充了通用结构优化程序DDDU(W)的功能。文末算例表明了算法的合理性与有效性。
This paper presents an approach to optimal design of a curved isoparametric shell elements with eight nodes and total of 40 freedoms. This approach is based on the transformation of non-linear programming into a sequence of quadratic programming (SQP). The DDDU(W) with a curved isoparametric shell elements is developed. Numerical results show that the method is efficient.
