Analysis of chatter vibrations in an automotive wiper assembly (Occurrence of Chaotic Vibrations in a region of low wiping speed)

摘要

In previous papers, chatter vibrations in an automotive wiper assembly were analyzed. First the equations of motion of a wiper assembly were derived by assuming that it is modeled by a two-degree- of-freedom system. Then the equations were solved for practical wiping speeds. The results showed that the equations could be used to explain the behavior of the wiper assembly. In this paper, the same equations are used to predict the behavior of the wiper assembly at low wiping speeds.
