With the drive of digital technology and the change of computer information technology, digital engineering technology is changing the traditional aircraft design process. Virtual test technology shows a trend of digitalization, intelligence and automation. Among them, the deep integration of CAE technology into virtual test process has become one of the most extensive technical practices in engineering applications. China Aircraft Strength Research Institute has carried out research on virtual display technology that can support physical tests of aircraft structures. It has independently designed related CAE graphic visualization algorithms and advanced data processing algorithms. It has broken through the test data monitoring and processing technology based on Qt multithreading and the rapid display technology of three-dimensional cloud images based on high-precision interpolation of test data, and is based on the independent CAE graphic engine SABRE.Prepost has realized the integrated research and development of the virtual display module for the static strength test of aircraft structures, and has been applied in the field of aviation model test, with remarkable results. This technology realizes the good combination of CAE technology and engineering application, innovates the new test mode of virtual reality integration, and also provides technical reference for virtual display and evaluation of multi discipline strength test in the future.
