To improve the design efficiency and model accuracy of aircraft maintenance training simulation device, a reverse modeling method using 3D laser scanning equipment and 3D modeling software is proposed. The point cloud data is obtained by the 3D laser scanner, and then imported into the 3D modeling software Geomagic studio. After generating surface,...

... the mesh generation function of the software, the point cloud data is generated into a mesh. The generated triangular mesh is as shown in Figure 5, which is composed of triangular surfaces connected by adjacent point clouds. The grid basically represents the overall profile of the joystick, but the surface quality is not high, and further improvement is needed. ...

Introduction:
Since the catapult of online learning during the COVID-19 pandemic, most simulation laboratories are now completed virtually, leaving a gap in skills training and potential for technical skills decay. Acquiring standard, commercially available simulators is prohibitively expensive, but three-dimensional (3D) printing may provide an a...

In the study of the mechanical behavior of naturally corroded steel, observations of the initiation-development-fracture process of stress concentration in rust pits are still limited. In particular, it is difficult to study the influence of corrosion on the high-temperature mechanical behavior of steel. In this study, the high-temperature tensile failure process of naturally corroded steel was reproduced using ABAQUS finite element analysis software by accurately scanning the morphology of the corroded steel surface and using numerical reconstruction technology. By using CREO (PRO/E) image-processing software to format the digital data STP of complex morphology, it is possible to realize the numerical reconstruction of corrosion morphology and maintain sufficient analysis accuracy. When a reasonable model grid size and fracture constitutive model are selected, the real test results can be restored to analyze and discuss the stress evolution induced by corrosion.
