The Redevelop Of Pro/E Assembly Interference Check

Assembly design is an important part of the product development process, along with the development ofcomputer technology, virtual assembly has become an important field of CAD technology research? the CADsoftware redevelop has also become an issue of CAD technology application and development In this paper,the theoretical analysis, algorithm design, computer programs develop and test are used to study the redevelopabout Pro/Engineer interference check in the virtual assembly.First, the background about the thesis is explained, the background, the basic concepts and features ofvirtual assembly is introduced. Then the research status and the existing problems which in domestic andoversea about virtual assembly, the interference check and general CAD software redevelopare analyzed.In this paper, the basic concept of virtual manufacturing the definition of virtual assembly technology andthe basic concept of virtual assembly technique involved is presented .Then the model and flow of virtualassembly system, the features and process about the virtual assembly and the key technologies of virtualassembly is analyzed in detail.The detection theory and methods is introduced, the check algorithm about the plane collision and spaceobject interference is explained? Then the computer model show and the spatial transformation matrix of athreedimensional objects is introduced. The concrete principles of algorithm about bounding box and severalother interference check algorithm is studied? the advantages and disadvantages of various algorithms and theprocess of calculating the amount of interference was also explained. Finally, the rapid and effective checkalgorithm about the validity of assembly path is explained, at the same time the implementation process ofdynamic interference check is explained by a algorithm example.The features of Pro/Engineer are briefed? the features and functions of Pro/Toolkit which attach toPro/Engineer are analyzed. The basic concepts which use Pro/Toolkit to redevelop are also explained, the specific implementation steps which use Pro/Toolkit to redevelop,the work mode of Pro/Toolkit and the link...
