Chatter vibration is sometimes observed in an automotive wiper. The objective of this paper is to explain the mechanism of the occurrence of chatter vibration. For this purpose, first, experimental analysis is conducted using a currently employed wiper. It is found that the chatter vibration is a kind of stick-slip motion, and it occurs in the second mode with two blades of the wiper deflecting in opposite directions. Next, by assuming that the wiper is modelled by a two-degree-of-freedom system, the equations of motion are proposed. By integrating them numerically, it is found that they well explain features of the chatter vibration observed in the experiment.
