The objective of this paper is to analyze chatter vibrations in an automotive wiper assembly which consists of two blades driven by a direct current motor via one link. For this purpose, first, the characteristics of the chatter vibrations in a currently used wiper are examined experimentally. Then, by assuming that the wiper is modeled by a two-degree-of-freedom system, the equations of motion are derived. They are solved for practical wiping speeds. By comparing the results with the experimental results, it is found that the derived equations well predict the experimental results. Based on the equations, it is concluded that the chatter vibration is mode-locked motion. Finally, the equations of motion are solved for lower wiping speeds. It is predicted that for these speeds, chaotic motion as well as quasi-periodic and periodic motion can occur.
