Abstract

The invention relates to a Virtools based multivariate data fusion virtual test display system, which comprises a data interface and processing module, a hybrid modeling and integrated module, a visual fusion display module, and a model correction module. A finite element method calculation (virtual test) and physical test methods carry out the calculation or test verification on all sub-structures, and a finite element model (virtual test model) is corrected according to physical test result data; meanwhile, a test trend indicated by the virtual test is utilized to guide the physical test to perfect the physical verification test scheme; finally, the overlapping display of comprehensive test environment of a complicated system is carried out according to a hybrid model established by a virtual test model and physical test data, and an LOD management technology is adopted in an overlapping display model, so that the overlapping display efficiency of physical field data in Virtools is improved.

Description

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