Research For Inverse Modeling Technology Of Aerostatic Ducts According To The Digital Manufacture

In tradition, the manufacture of aerostatic ducts is based on the physical ducts. Thismethod has a lot of shortcomings, such as the deforming caused by the long-term suspension,and the occupation of human resources to manage them, these all not only directly orindirectly affect the quality of ducts, but also are harmful to the modern production of aircraft.Today, by the dramatically developing of digital manufacturing technology, the digitalmanufacture of aircraft gets more and more people’s attention. This approach has a lot ofadvantages such as high manufacturing precision, high production efficiency, saving resources,reducing production costs. But to achieve digital manufacture of aircraft, the prerequisite is toachieve digital manufacture of aerostatic ducts.Under the background of digital manufacturing, this article is about digital reversemodeling of ducts which are used in the planes. By using the articulated arm measuringmachine, we can get the point data of this object. By the simply processing of GeomagicStudio reverse software, and finally importing into CATIA reverse modeling module, we canget the final reverse modeling. In order to standardize the process of modeling, as well as toimprove the processing efficiency and quality of inverse modeling, we can use CATIAsecondary development technology when we use CATIA. This research specific includes theclassification of aerostatic ducts, the manufacturing method and the process of the review, theinverse modeling methods of ducts, and inverse modeling of key technologies, and theassembly of ducts. The ultimate goal of this project is to achieve the reverse modeling ofsingle ducts, standard half ducts, nonstandard half ducts, and duct connectors, assembly themas duct components, transfer all physical ducts into digital models, and finally replacephysical ducts as the manufacturing basis.
