“…Thus the dependent variable can be expressed in the form of a scaling law, Equation (10) in Table 2, where < is the characteristic length of the system. This mathematical form enables the main behavior of mechanical [22] or mechatronic components [23] to be represented in a simple way. The SLAWMM method [24,25] extends the validity of scaling laws by replacing the = and : constant coefficients in equation 10by functions of numbers (Equation 11in Table 2).…”

This paper presents an original form of surrogate models and the associated construction procedure adapted to the thermal modeling of Multiphysics systems. This method of meta-modeling, which uses dimensional analysis, extracts compact models suitable for preliminary design from finite element simulations. The mathematical expression used for the model is a product of variable power laws of dimensionless numbers. Compared to traditional surrogate models (polynomial response surfaces, kriging and radial basis functions), it has the advantage of giving light, compact forms with good predictive accuracy over a wide range of the design variables (several orders of magnitude). The general regression process is first explained and illustrated with a study of the Marangoni effect. Then the methodology is used to build thermal models of an electromechanical actuator (EMA) which are used to size an aileron EMA for two different cooling strategies. Finally the models are also used to discuss the effect of confinement on the actuator's overall thermal resistance.

“…Scaling laws have assets that make them attractive for the design of mechatronic systems [22] [23] [9]. Their simple form makes them easy to manipulate and customize as they require only one reference to determine the multiplier coefficient k, the power coefficient a being determined by the physical phenomena.…”

Scaling-law-based metamodels for the sizing of mechatronic systems

This paper presents a new metamodel form and associated construction procedure adapted to the sizing tasks of mechatronics systems. This method of meta-modeling uses scaling laws to extract compact forms of design models from local numerical simulations (FEM). Compared to traditional metamodels (polynomial response surfaces, kriging radial basis function) the scaling-law-based metamodels have the advantage of a light, compact form and good predictive accuracy over a wide range of the design variables (several orders of magnitude). The general regression process is first explained and then illustrated on different examples: a purely numerical test function, a limited angle electromagnetic actuator and a flexible mechanical hinge.

“…Actuation of high lift systems [3] enable directional changes in the shaft routing while universal joints, spline joints, and plunging joints compensate directional changes and length variations resulting from wing bending and temperature effects. Branch gears connect the actuator drive stations to the main transmission system.…”

High lift actuation system design is a highly iterative process. Especially the preliminary design phase, which sets the course for the following design steps, is characterized by uncertain and changing data input. Despite the importance of this early design phase, a specialized and integrated computational support is not available. The objective of the research project WissBaSys is to offer knowledge-based design assistance focused on the preliminary design of high lift actuation systems. Moreover, information concerning a specific drive system architecture and component data can be used for an automated model generation leading to a significant time reduction and enhanced traceability. A capable approach for order reduction of shaft transmission models, as well as the concept for computer-aided modelling, is presented in this article.
