Abstract:
A method for producing a flexible mechatronic system includes: a step of modeling the system by a mesh including a given combination of elementary blocks, each block being formed of a predefined assemblage of segments representing elementary beams, the mesh including at least one active block controllable by means of a control signal; a step of simulating the behavior of a terminal node of the model in open-loop response to a control signal; a step of characterizing said response by at least one static mechanical criterion and at least one numerical criterion representative of the decay of the resonance spikes of the response as a function of frequency. The above steps may be repeated. The method further includes a step of selecting a design as a function of the criteria defined in the characterization step, the system being produced on the basis of the selected model.
