Dynamic behavior of a small wiper with piezoelectric actuators, which is applied for a small CCD camera, is discussed in order to clarify the driving mechanism of it. First, the analytical governing equations are evaluated in the distributed system using the eigen function expansion techniques. Second, a flexible multibody method based on the absolute nodal coordinate formulation (A.N.C.F.) that has been proposed by Ahmed. A. Shabana et al. is introduced as a numerical test and formulated using the general augmented formulation of the equations of motion. In addition to the numerical analysis, present wiper is verified experimentally. In conclusion, the driving mechanism of the present wiper module enables us to explain the effect qualitatively and quantitatively.
