Abstract:
In the static test of the frame of liquid rocket engine, lots of displacement sensors are usually arranged at the key positions to measure the displacement of the frame.The displacement data measured are analyzed to determine whether the frame meets the stiffness design requirements.Because of the large number of displacement sensors, it is difficult to find possible abnormal points intuitively and quickly.At the same time, it is difficult to analyze the overall deformation of the frame because of lack of visualization.So a three-dimensional visual deformation analysis technique for static test was proposed.The continuous three-dimensional deformation of the structure in the loading process was reconstructed using the geometric positions of the structure and the displacements of the measuring points.The three-dimensional deformation animation of the structure was obtained.Based on the software platform of matlab, the software of spatial deformation analysis was developed, which is intuitively to analyze the overall deformation of the structure and find the abnormal points.The results of analysis can also be saved as document files and video files.Results show that the developed technique is helpful to judge whether the displacement data of the measuring points are abnormal, and is valuable for intuitively analyzing the overall deformation process of the frame in static test.
