Abstract

Wiper is a device to wipe out dirt and raindrops from the windscreen. Hence, when a wiper system is operated, it has a potential to generate unwanted noise and vibration level. Reversal is one of the noise and vibration generated during the wiper operations. It is a medium frequency and self excited vibration that is often generated before and vice versa the direction. This leads to poor visibility and annoying sound to the driver and passengers. This paper investigates the effect of friction coefficient on vibration response in the wiper assembly. The adjusted values of friction have been made in order to reduce the noises and vibrations level. Besides, an input shaping (IS) control technique is proposed to reduce the reversal noises and vibrations level in this wiper system. A two dimensional mathematical model of wiper system is used in this analysis which shows that the noise and vibration level can be reduced up to 30 percents.
