Generation des sequences d'assemblage d'un produit a partir de sa modelisation dans CATIA et AutoCAD (French text)

It would be very useful for industry to make use of a software that is able to generate and evaluate automatically all the feasible assembly sequences of any product, i.e. to find the order and direction of assembling each of its components. In this project, we have obtained the above directly from the assembly drawing in AutoCAD or CATIA. We have chosen these two CAD softwares because they are very commonly used in industry.; The application that we have developed is called Polyassemblage. It is able to generate and evaluate all feasible assembly sequences of a product given its solid representation. It is compatible with CATIA V5 on Windows and AutoCAD (releases after 14). Polyassemblage is user friendly and gives good results for the examples we tested (assemblies with around 10 components). Polyassemblage uses the automation interfaces provided with CATIA and AutoCAD to extract the information about the geometry of the assembly.; The program can look for means of disassembly: it moves each element step by step in a given direction and checks that it does not collide with any of the other solids. With this information the program is able to generate all the assembly sequences. (Abstract shortened by UMI.)...
