Objective The main objective of the project was to develop an open architecture design system based on the BOSS-Quattro system and devoted to shape and sizing optimisation of three dimensional structures. This architecture allows the users to introduce within the optimisation loop their own specialised "in-house" software as well the commercial products like parametric CAD CAE systems, with special attention to: parametric CAD systems (Pro-Engineer, Catia etc.) mesh generators (MSC/Patran) analysis modules (Samcef, etc.) so that this existing technology can take advantage of new capabilities for optimisation at minimum extra-costs. Communication between commercially available software is treated through a standardised set of drivers, specialised for each type of information having to be exchanged (parameters, model's responses, sensitivities, etc.) The scope of the project embraces: Optimisation with structural functions related to: maximal stresses, strains, multi-layered composites data, weight minimisation, eigen-frequences, etc. Multi-model optimisation: simultaneous optimisation of several analysis models, ie of several aspects of the structural behaviour (static, dynamic,) Multi-discipline optimisation Shape optimisation (2D and 3D) involving CAD systems. Treated of mixed design variables: global or local shape parameters (dimensions) and sizing ones (physical, material properties) Sensitivity analysis both with finite difference scheme and integrated methods (semi-analytical) Control of the numerical error level Treatment of model up-dating problem through the optimisation kernel Open architecture and use of computer networks Based on the BOSS-Quattro system, customised solutions have been developed and installed in the end-users allowing them to complete an extensive test program of the new technology.The main objective of the project is to develop an open architecture design system based on a set of subtools communicating through a central Data Base and developed to optimization of 3-D structures. Below the man-machine interface, a kernel will be developed allowing users to introduce within the optimization loop their own specialized "in house" software so that they can take advantage of new capabilities for optimization at minimum of extra-costs. Communication between commercially available softwares will be effected in the new system using existing standards.The expected scope of the optimization environment will embrace:- structural constraints related to : maximal stresses, strains, etc., weight minimization, eigen frequenties, dynamic transient response, buckling loads; - users defined explicit constraints; - multimodel, multidiscipline optimization; - automatic sizing of thin-walled structures; - automatic choice of material distribution; - optimization of multi-layer materials; - 3-D shape optimization(volumes and surfaces); - trade-off design, sensitivity of the optimum.A pilot system will be designed and developed. This will handle all procedural aspects and permit industrial end-users to complete an extensive test program for the new system. The following field of application will be addressed : correlation problems, control of the numerical error, automatic choice of material, 3-D volumic shape optimization, user defined constrains concerning fatigue life, manufacturing, and process (multi-disciplinary), etc.Benefits will be obtained first by a decrease of computational costs of the design teams of at least 20%, second by an enhancement in the quality of the design products and third by marketing of the commercial implementation of the design code itself.
