Project and Construction of a Measuring System to Determine the Forces Applied to Automotive Airfoils 2011-36-0275
This paper presents a system developed for measurement of force, based on a load cell. The aim was to design a device capable of measuring the components of the force, drag and lift, which acted over automotive spoilers. In order to enable the system to measure the drag and the lift force, it was necessary to develop a system capable of measuring only the components of interest, uncoupling efforts, such as multiple solicitations and vibration. Measurements of force were carried out over an airfoil, employing the measuring system described in this paper. The results showed that the values of the forces that acted over the airfoil were in agreement to the expected. Airfoils are used mainly in automotive racing cars to increase adherence between the tires and ground. Car prepares have made use of theirs experience to determine the best type and angle of attack for the airfoils. With the help of system developed by the authors, preparers of racing cars can measure the efforts and know their effects over the cars.
