Dynamic Analysis of Blade Reversal Behavior in a Windshield Wiper System 2000-01-0127

The blade impact force at the top and bottom reversal points contributes significantly to wiper system noise. This paper describes a newly developed process to simulate blade reversal behavior. The results of this simulation can provide necessary insight into reducing blade reversal noise.
As a result of simulation under various conditions, it is shown that the reversal impact force can be reduced by modifying the maximum rubber neck rotational angle and the rubber neck rotational spring constant. It is also shown that the reaction force at the top and bottom reversal points can be adjusted by modifying the arm head twist angle.
