三维数字图像相关在旋转物体变形测量中的应用
Deformation measurement of rotating object using three-dimensional digital image correlation
摘要
Abstract
Rotating structures are commonly used in the transportation and energy generation fields.As a non-contact optical measurement technique,the Three-Dimensional Digital Image Correlation(3D-DIC)allows for the full-field spatial measurement of displacement,deformation and vibration of rotating objects in operation,which provides important data support for damage detection,health monitoring and aerodynamics structural optimization design.A review of the extensive studies on the development and application of 3D-DIC is presented.First,the principle of 3D-DIC and its rotating object measurement setup are introduced.Particularly,in cases when the deformation involves a large rotation,a de-correlation problem emerges.To address this,many scholars have proposed initial value estimation and shape function design methods for large-rotation objects,which are investigated extensively here.Several application cases utilizing 3D-DIC for damage detection and vibration measurements are introduced,showing its unique advantages compared with traditional deformation measurements methods.Lastly,the applica-tion prospect and development trend of this technology are prospected.关键词
