Modelling approaches for the simulation-based preliminary design and optimization of electromechanical and hydraulic actuation systems

Abstract

This communication proposes to combine non causal modeling, metamodeling and scaling laws in order to take advantage of the inverse simulation capabilities of recent system level simulation software with the main target to assess technological alternatives quantitatively from a limited set of required data. The scaling laws are illustrated here for major hydraulic components (hydraulic cylinders and pumps) and are validated with manufacturers’ data. The proposed methodology is illustrated with the preliminary sizing of an electro-hydrostatic actuator driving an aircraft primary flight control surface (aileron). The design exploration for geometrical integration and mass is realized using to surface response models.
