飞行器总体设计是一项复杂系统工程,多专业、强耦合是其特点。针对飞行器总体快速设计需求,提出基于响应面更新的协同优化方法。通过将临时最优解纳入输入输出样本对方法,逐步更新响应面模型,并利用协同优化方法对复杂系统进行分解寻优。以某飞行器为应用对象进行优化设计,结果表明该方法能够快速获得最优解,提高求解效率。
Aircraft overall design is a complex system engineering, multi-specialty, strong coupling is its characteristics. Aiming at the requirement of overall rapid design of aircraft, a collaborative optimization method based on response surface updating is proposed. By incorporating the provisional optimal solution into the input and output samples, the response surface model is gradually updated and the complex system is optimized by using the collaborative optimization method. The optimization design of an aircraft is made. The results show that this method can obtain the optimal solution quickly and improve the solution efficiency.
