A platform system for the integrated design of aircraft structure and function based on uncertain optimization

Abstract

The invention discloses an aircraft structure function integrated design platform system based on uncertain optimization. The aircraft structure function integrated design platform system is composed of a system framework program and seven sub-modules comprising a pneumatic shape design optimization module, a forecabin thermal protection system design optimization module, a wing thermal protection system design optimization module, a composite cooled structure design optimization module, a wing heat-protection load-bearing integrated structure optimization module, a wing pneumatic / structure / thermal coupling optimization analysis module and a basic database module. An integrated design of the platform is achieved on the basis that certain analysis optimization and uncertain analysis optimization of system functions of each structure are carried out. The platform integrates an aerodynamic force / heat database, an integrated model database and various algorithms into the system, and a convenient tool is provided for non-professionals to carry out an integrated design.

Description

technical field [0001] The invention relates to an aircraft structure-function integrated design platform system based on uncertain optimization, and belongs to the technical field of uncertain multidisciplinary optimal design. Background technique [0002] Uncertainty multidisciplinary optimization design technology is complex and computationally complex due to the inherent loop characteristics of data transmission. Uncertainty is coupled and propagated in multiple discipline subsystems, making multidisciplinary optimization design based on uncertainty The practical application of it has become a challenging topic. [0003] At this stage, the uncertain structure-function optimization design of structures is mostly realized by integrating the required software and algorithms in a general multidisciplinary optimization design environment. [0004] The multidisciplinary optimization design environment refers to the design computing environment that integrates the analysis mod...
