Abstract

The invention discloses a missile and engine integrated multi-disciplinary design optimizing method based on variable correlation. The method includes the steps of establishing a quantitative hyper-ellipsoidal model of variable correlation according to variable intervals, establishing a missile and engine integrated multi-disciplinary collaborative optimizing model through a collaborative optimizing method, establishing a missile and engine integrated multi-disciplinary design optimizing model under variable correlation conditions, and conducting solving. By combining the hyper-ellipsoidal model with the interval theory, the problem that due to the correlation between artificial divided variables, the design structure is not accurate is solved, and then the actual design requirement of the product can be better met.

Description

Technical field [0001] The invention belongs to the technical field of multidisciplinary design optimization of mechanical products, and in particular relates to an integrated multidisciplinary design optimization method of missile and engine based on variable correlation. Background technique [0002] The overall design of the missile weapon system is a multi-disciplinary and highly integrated large-scale system engineering. Its content involves a wide range, a large amount of calculation, and a long development period. It is a process of multiple iterations, comparisons, and integration. [0003] With the development of modern optimization algorithms, distributed network computing technology, and parallel engineering theory, the analysis theories of various disciplines have been continuously improved. Since the 1990s, multidisciplinary optimization technology has been rapidly developed abroad. Multidisciplinary Design Optimization (MDO) is the latest and most active field of airc...
