摘要
给出了航空发动机涡轮盘榫槽的形状优化设计的数学模型，并用参变量评价函数法对该数学模型进行等价转换。用基于两点累积信息的原／倒变量展开的对偶优化方法ＤＥＯＲＣＴ对该问题进行求解。算例验证了本文思想及方法的正确性。
A mathematical mode is proposed of the shape optimum design of engine′s turbodisk tenon-grooves, which can be transformed equivalently by using parametric evaluational functions. The dual method by expansion of original/reciprocal variables based on the cumulative information at two points is applied to solve the problem. The ideas and the method of the present paper have been verified by numerical experiments.
