Abstract

The invention provides a CFRP air guide sleeve integrated design method based on variable coupling and software integration. The CFRP air guide sleeve integrated design method comprises the steps thatvariable coupling operation is conducted on design variables; geometric modeling is carried out in the SIEMENS NX, and the established geometric model is transmitted to the CFD; aerodynamic mesh generation is carried out on the geometric model in ICEM CFD; flow solving is carried out on the divided aerodynamic grids in ANSYS FLUENT to calculate a surface flow field of the air guide sleeve; a CFRPlayer in the part in the APDL is modeled, and a genetic algorithm is compiled to optimize a layer angle through initial layer design; and structural finite element modeling is performed in the APDL,and ANSYS is called to analyze the model. According to the method, cooperation of multiple disciplines such as part macrostructure disciplinary optimization, microcosmic material layering disciplinaryoptimization and fluid dynamics can be considered at the same time, and the parts are integrally designed.

Description

technical field [0001] The technical field of integrated optimization design of the present invention particularly relates to an integrated design method of CFRP shroud based on variable coupling and software integration. Background technique [0002] In related technologies, it is often considered how to optimize the design of components in a single discipline to optimize the required functions, but the design of components often involves multiple disciplines, such as: the field of mechanical structure optimization design, the field of material internal mesostructure optimization design, Aerodynamics and Fluid Mechanics etc. At present, structure, material and function are not considered at the same time in the lightweight design of parts. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an integrated design method of CFRP shroud based on variable coupling and software integration, which can simultaneously ...
