Item Integrating structural and input design of a 2-DOF high-speed parallel manipulator: A flexible model-based approach(2010-11) Da Silva, Maíra M.; De Oliveira, Leopoldo P.R.; Brüls, Olivier; Michelin, Micaël; Baradat, Cédric; Tempier, Olivier; De Caigny, Jan; Swevers, Jan; Desmet, Wim; Van Brussel, Hendrik; Tecnalia Research & InnovationThis paper discusses the integrated design of parallel manipulators, which exhibit varying dynamics. This characteristic affects the machine stability and performance. The design methodology consists of four main steps: (i) the system modeling using flexible multibody technique, (ii) the synthesis of reduced-order models suitable for control design, (iii) the systematic flexible model-based input signal design, and (iv) the evaluation of some possible machine designs. The novelty in this methodology is to take structural flexibilities into consideration during the input signal design; therefore, enhancing the standard design process which mainly considers rigid bodies dynamics. The potential of the proposed strategy is exploited for the design evaluation of a two degree-of-freedom high-speed parallel manipulator. The results are experimentally validated.
