Abstract

The present invention relates to a multivariate data fusion virtual test display system based on Virtools. The system includes a data interface and processing module, a hybrid modeling and synthesis module, a visual fusion display module, and a model correction module. It adopts finite element calculation (virtual test) and In the way of physical test, all substructures are calculated or tested respectively, and the finite element model (virtual test model) is corrected according to the data of the physical test results. At the same time, the test trend predicted by the virtual test is used to guide the physical test, and the physical verification test plan is improved. According to the mixed model constructed by the virtual test model and the physical test data, the overlay display of the comprehensive test environment of the complex system is carried out, and the LOD management technology is adopted in the overlay display module to improve the efficiency of the overlay display of physical field data in Virtools.

Description

technical field [0001] The invention relates to a multivariate data fusion virtual test display system based on Virtools, which belongs to the technical field of computer simulation. Background technique [0002] With the widespread application of contemporary large-scale and complex structures (such as rockets, offshore oil platforms, large buildings, long-span bridges, etc.) in engineering, the requirements for structural modeling technology are getting higher and higher, and the difficulty is also increasing. The large-scale structure determines the inefficiency of traditional finite element analysis and calculation of the whole structure, and requires the adoption of sub-structure comprehensive modeling technology. At the same time, since there are a large amount of test data for some important components in the project, how to effectively use these test data to integrate it with other components in the system, realize the mixed modeling of the system, establish the dyna...
