Abstract:
The increasing demand in fast innovations to obtain news functionalities and a higher efficiency in air transport drives the development and design of embedded systems. In this context, conventional hydraulic actuation systems tend to become more electrical. This communication proposes an innovative and fully integrated methodology that aims to assess actuator architectures during the preliminary design. This fully integrated method enables a comparison of mass, dimensions and reliability of different architectures with knowledge of geometric integration, essential for the designer. The proposed approach is based on the joined use of inverse and direct simulations together with scaling laws representative of the physical phenomena driving electromechanical component sizing. With the examples of the rolling and spherical bearings, this communication illustrates the process to establish such scaling laws, along with their validation with respect to manufacturer d¬¬¬ata. Sizing models and non-causal simulation models (for direct and inverse simulations) are implemented with the Modelica language to realize a library of electromechanical power transmission components. This library is used as a software tool supporting the designer in the assessment of actuator architectures. The efficiency of the proposed methodology, modeling approach and software tool is illustrated with the assessment of two different architectures for an electromechanical airbrake actuator.
