The objective of SYNCOMECS is to build an integrated software, using inverse methods, for the design of aeronautical compliant mechanical systems from industrial specifications of functional requirements. The design of these innovative systems poses unique challenges and necessitates the support of advanced prediction software tools since they should have adequate flexibility to undergo desired deformations under the action of applied forces and adequate stiffness to withstand external loading. The focus is to generate the topology and dimensions of a compliant mechanical system starting from input/output force/displacement functional requirements and design constraints. This problem is a non-linear optimisation problem of a non-linear mechanical system that may involve one or several flexible components. In a general case, it involves Optimisation, Multi-Body Simulation and Non-linear Finite Element Analysis. The solution may be non- existent and, if it exists, not necessarily unique. Software to be develope d will be applied to aeronautical industrial problems. R&D activities will be executed in four steps. Firstly, a full specification of the system will be made. The result of this step will be presented at Milestone 1. The second step will be the develo pment of separate modules and the simultaneous preparation of benchmarking models. The results, as standalone software tools & associated benchmarks, will be validated at Milestone 2. The third step will be the integration of the separate modules withi n the SYNCOMECS system. The result will be validated at Milestone 3. The fourth step will integrate the outcome from evaluation of the end-users. At this level, Milestone 4, the interaction between developers and end-users will lead to the final validation of an integrated environment for synthesis and analysis of compliant mechanical systems.
