Wind Tunnel Robot
The German-Dutch Wind Tunnels (DNW) is a non-proft foundation under Dutch law. DNW operates its own Large Low-speed Facility (LLF) and the aeronautical wind tunnels of the German Aerospace Center (DLR) and the Dutch National Aerospace Laboratory (NLR). These wind tunnels are located in Germany and the Netherlands. The main objective of DNW is to provide the customer with a wide spectrum of wind tunnel test and simulation techniques, operated by one organization, providing the benefts of resource sharing, technology transfer, and coordinated implementation of research and development results.
A start was made by collecting the geometric data and physical parameters of the robot (i.e. lengths, masses, inertia parameters etc.). using these parameters, a 3D model was created using the modeling and simulation package 20-sim. The package allows you to enter 3D mechanical models by giving the position of joints, mass parameters etc. out of this data, a dynamic model is automatically generated. During simulation this models use the joint torques and wind loads as input and returns the corresponding motion of the
robot as outcomes. The validity of the model is ensured by using the physical laws of motion as a mathematical framework for thegeneration of the dynamic model.
