In order to improve the efficiency of the general platform optimization, a new mean value-based collaborative method (MVCM) for structural optimization of general platform is proposed. The key idea of this method is to decompose the general platform optimization problem into a system-level optimization problem and several independent subsystem-level optimization problems by introducing coordination variables. While meeting the design requirements and performance requirements, the subsystem optimizes each aircraft so that the design variables of each aircraft are as close as possible to coordination variables. The system-level coordination adjusts the coordination variables according to the results of each subsystem. With the continuous iteration between the system and the subsystems, the coordination variables that can maximize the generality of the product family are finally found. The numerical test results show that the MVCM can greatly improve the efficiency of the general platform optimization.

基于均值的飞机族结构优化协同方法

为了提高通用平台优化的效率，提出了一种新的基于均值的通用平台结构优化协同方法（MVCM）。该方法的核心思想是通过引入协调变量将一般平台优化问题分解为一个系统级优化问题和几个独立的子系统级优化问题。该子系统在满足设计要求和性能要求的同时，对每架飞机进行优化，使每架飞机的设计变量尽可能接近协调变量。系统级协调根据各个子系统的结果调整协调变量。随着系统与子系统之间的不断迭代，最终找到了能使产品族的通用性最大化的协调变量。数值测试结果表明，MVCM可以大大提高通用平台优化的效率。
