Problems solved by technology

The entire display interface is presented in the form of a two-dimensional table. The loading point force feedback, pressure feedback, displacement feedback and other data are indexed by the loading point number, which cannot directly correspond to the loading position. The test control personnel and test commanders observe the loading point force feedback, For the accuracy, stability and symmetry of pressure feedback and displacement feedback, it is necessary to manually determine the position of the loading point according to the "Notice of Loading Equipment Use", the acquisition of feedback data information and comprehensive research and judgment have obvious lag, and the display of feedback data is intuitive There are obvious deficiencies; the test operation information such as line number, load, and landing number is indexed by the test attributes, and the efficiency of information acquisition by test schedulers and managers is obviously insufficient when scheduling tests

Abstract

The invention belongs to the technical field of airplane complete machine strength tests, and discloses a test data three-dimensional display method based on data fusion. The method comprises the following steps: S1, acquiring test data, wherein the test data comprises test loading data and test machine deformation data; s2, establishing a three-dimensional model of the testing machine; s3, displaying the test data at the corresponding position of the test three-dimensional model in real time, so that the accuracy, stability and symmetry analysis efficiency of test force feedback, pressure feedback and displacement feedback data can be greatly improved; and meanwhile, the visual display and playback capabilities of test force feedback, pressure feedback, displacement feedback data and testoperation information such as row number, load and rising and falling number can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft strength testing, in particular to a three-dimensional display method of test data based on data fusion. Background technique [0002] During the structural strength test of the whole machine, data such as force feedback, pressure feedback, displacement feedback, and test operation information are collected by the coordinated loading control system and displayed on the professional data display interface. The entire display interface is presented in the form of a two-dimensional table. The loading point force feedback, pressure feedback, displacement feedback and other data are indexed by the loading point number, which cannot directly correspond to the loading position. The test control personnel and test commanders observe the loading point force feedback, For the accuracy, stability and symmetry of pressure feedback and displacement feedback, it is necessary to manually determine the position ...
