Abstract

The invention discloses a multidisciplinary design optimization method for missile and engine integration based on variable correlation; it includes constructing a quantitative hyperellipsoid model of variable correlation according to variable intervals, and using a collaborative optimization method to establish multidisciplinary coordination of missile and engine integration Optimizing the model, building and solving the integrated multidisciplinary design optimization model of the missile and the engine under variable-related conditions. The invention combines the super ellipsoid model with the interval theory, solves the problem of inaccurate design results caused by artificially splitting the correlation between variables, and thus can better meet the actual design requirements of products.

Description

technical field [0001] The invention belongs to the technical field of multidisciplinary design optimization of mechanical products, and in particular relates to a multidisciplinary design optimization method for integrated missiles and engines based on variable correlation. Background technique [0002] The overall design of the missile weapon system is a multidisciplinary and highly integrated large-scale system engineering, which involves a wide range of areas, a large amount of calculation, and a long development cycle.
