摘要
研究缠绕复合材料发动机壳体在内压载荷作用下，承受强度约束的优化设计方法。对强度约束采用Ｔｓａｉ－Ｗｎ失效准则，使各铺层的强度比Ｒ都临界满足强度准则。从而导出最有利厚度的选代公式。通过算例表明，本文所提供的方法具有较高的效率，结构重量稳定下降。一般经过１～６次迭代计算即可达到优化设计。
Design optimization algorithm of winding composite motor cases under inner pressure and endure strength restrain is studied. Tsai-Wn Failure Criteria is taken in order that strength ratio of each layer can satisfy the strength criteria. Then the iteration formula of optimal thickness is derived. Examples show that the algorithm presented in this paper is efficient. Structural weight drop steadly. After 1～6 iteration computation, design optimization can be gotten.
