The invention discloses an aircraft multidisciplinary optimization
design integration system based on OpenMDAO, and belongs to the field of multidisciplinary optimization design. The
system comprises the following modules: a subject establishment module, a
coupling analysis module, an experiment design module, an optimization design module and a
data modeling module. The subject establishment module automatically generates an OpenMDAO component through input, output and
computational logic defined by a user. And the
coupling analysis module automatically generates an expansion structure matrix and an N2 graph according to the subject selected by the user, so that the user can carry out multidisciplinary
coupling analysis. The experiment design module carries out experiment design and
sensitivity analysis according to the experiment design method of the selected subject and
system integration. And the optimization design module allows a user to select a subject, set a design variable, an optimization target and a constraint condition, and perform multidisciplinary optimization. The
data modeling module uses historical data generated by experimental design to carry out
data modeling through an integrated modeling method, and the model is used for experimental design and optimization to balance the contradiction between calculation precision and quick response. According to the method, automatic establishment and calling of the OpenMDAO
assembly in the overall
design process of the aircraft are achieved, a user does not need to deeply know an OpenMDAO frame and an
algorithm thereof, analysis and optimization of multidisciplinary problems can be rapidly completed only by defining input and output information of the disciplinary, and an efficient and convenient tool is provided for multidisciplinary optimization design.
