(I) Automotive Industry

The BMW Group has pioneered the application of industrial CT technology in prototype vehicle R&D, production and failure inspection analysis, breaking the traditional detection method that required vehicle disassembly for fault diagnosis. Industrial CT verifies whether the internal structures and dimensional parameters of automotive components meet specifications. It can scan the whole vehicle to check if the overall body appearance conforms to design standards, and meticulously inspect the assembly status of numerous internal parts, structural surface conditions, as well as pores, gaps and other defects that may compromise overall structural stability, so as to accurately determine the qualification of finished vehicles. Meanwhile, the 2D or 3D images generated by industrial CT will not be obscured by surrounding features, enabling direct acquisition of the spatial position, shape, dimension and other data of target components. The density resolution of high-quality CT images can reach 0.3%, at least one order of magnitude higher than that of conventional non-destructive testing technologies. Equipped with high-performance detectors, industrial CT delivers a dynamic response range above 10⁶, far superior to X-ray films and image intensifiers. In addition, CT images are easy to store, transmit, analyze and process. Apart from obtaining the shape, position and dimension of defects, combined with density analysis technology, industrial CT can also identify defect types, providing comprehensive evidence for automotive quality control.

(II) Aerospace Industry

The aerospace industry imposes extremely stringent quality requirements on components, which can be well satisfied by industrial CT inspection technology. In the development of aero-engines, the launch of carrier rockets, spacecraft and other aerospace vehicles, industrial CT performs high-precision measurement and analysis on key components to guarantee flight safety. It verifies the structural integrity of engine interiors and the dimensional accuracy of parts. With the coordinate measurement module of VGSTUDIO MAX, single aircraft engine components such as shafts, pistons and various valves can be measured without engine disassembly, which is especially applicable to castings with complex internal cavities — a capability impossible for traditional coordinate measuring machines. During component production and in-service maintenance, industrial CT is widely used to detect typical casting defects including cracks, shrinkage porosity, blowholes and inclusions in turbine blades, aero-engines, landing gears, hydraulic systems and fuselage materials. Furthermore, industrial CT efficiently and accurately visualizes the internal composition and assembly relations of assembled parts for intuitive analysis of internal structures and assembly tolerance gaps. The wall thickness analysis module of VGSTUDIO MAX enables automatic detection of regions with insufficient or excessive wall thickness and clearance width in aero-engine parts, displayed via color coding to support casting process optimization, mold modification and failure analysis of test workpieces.
