Mean Value-Based Parallel Collaborative Optimization Method for Modular Aircraft Structural Layout

The conventional structural layout optimization method is usually used to solve the problem of a single structure, but it difficult apply modular aircraft structure containing multiple substructures. Therefore, this paper proposes mean value-based parallel collaborative (MVPM) for layout. This two-stage based on decomposition. basic idea MVPM decomposing into system coordination and several independent subsystem problems by introducing variables. optimizes each structure. Under constraints itself, performance better, shared variables are as close possible. adjusts according results subsystem. With constant iteration between subsystems, eventually agree with numerical test show that has high efficiency stability.
