Simulation of Aerodynamic Uplift Consequences on Pressure Repartition – Application on an Innovative Wiper Blade Design 2001-01-1043
For wiper systems on automobiles, poor wiping at high vehicle speed is mainly due to lack of pressure under the blade caused by aerodynamic lift. This paper describes a method using aerodynamic simulation results in a mechanical calculation. The calculation purpose is to determine the consequences of aerodynamic uplift on pressure repartition under a wiper blade positioned on a car windshield. We illustrate this method by comparing the results of an innovative wiper blade design with the one of a classical blade.
