摘要/Abstract

摘要： 为了解决协调器优化设计中的不足，提出了基于参数区间不确定分析的保性能优化方法。该方法考虑工程设计中关键尺寸或材料参数变化的区间性，通过将参数区间变化从参数变差空间映射到目标和约束空间，得到的目标和约束性能退化估计作为原优化问题的附加约束，形成外层、内层的优化结构。某火炮协调器的优化结果证明了该方法在解决具有参数区间不确定的复杂工程优化问题上的有效性。

Abstract: A guaranteed cost optimization method based on analysis of parameter interval uncertainties is proposed to overcome the disadvantage in design optimization of shell transfer arm. In this proposed method, the interval characteristic of key dimensions or material parameters in the engineering design is considered, and the parameter perturbations are mapped from variation space into objective and constraint spaces, then the obtained degraded-estimation of objective and constraint is acted as an additional constraint of original optimization problem, resulting in a new robust optimization of an outer-inner optimization structure. The optimization results of shell transfer arm show that the proposed method is effective in solving complex engineering optimization problems with interval uncertainties.
