Abstract

The invention discloses a modeling algorithm for a three-dimensional mesoscopic model of closed-cell aluminium foam. Binary aluminium foam X-CT sequence images are processed through adoption of an improved XCT image processing algorithm, and the images are converted into a UnsignedChar format; aluminium foam volume attributes are set; the three-dimensional mesoscopic model is drawn; volume data ismapped into screen images; and the three-dimensional mesoscopic model is displayed. According to the modeling algorithm, the cell hole adhesion problem in the XCT images of the closed-cell aluminiumfoam can be effectively solved; a cell hole air three-dimensional mesoscopic model and a cell wall three-dimensional mesoscopic model of the closed-cell aluminium foam can be accurately and reliably established according to the three-dimensional mesoscopic model of the closed-cell aluminium foam established based on the XCT images, and the established models are completely consistent with a true mesoscopic structure of the closed-cell aluminium foam.

Description

technical field

[0001] The invention belongs to the technical field of X-CT (X-ray-computerized tomography) image processing of multicellular materials, and specifically relates to a three-dimensional microscopic model modeling algorithm of closed-cell foamed aluminum. Background technique

[0002] Closed-cell aluminum foam is a lightweight porous material that has been widely used in engineering due to its excellent mechanical properties. For the closed-cell aluminum foam material, it is mainly composed of the matrix material and the air enclosed in the cells. Due to the randomly distributed mesoscopic structure, its mechanical properties show typical multi-scale characteristics. It is necessary to develop a method that can truly reflect A 3D mesoscopic model of its mesostructural properties.

[0003] Professor Zheng Zhijun of the University of Science and Technology of China used the 3D Voronoi technology to invent the 3D mesoscopic model of the closed-cell foamed aluminu...
