Analysis of Friction-Induced Vibrations of a Xerographic Cleaning Blade
Abstract:In this article, friction-induced vibrations of a xerographic cleaning blade are investigated theoretically and numerically. Using a finite element model, eigenvalue analysis of the blade vibration is conducted considering the friction force between the cleaning blade and the photoreceptor. It is indicated that two different mechanisms exist for the cleaning blade vibrations: the negative speed dependence of the friction coefficient and the friction induced coupling of certain vibration modes. Numerical analysis is carried out for a typical blade, and the unstable vibration modes are predicted for both mechanisms. Simulations are performed to verify the results of the eigenvalue analysis and to obtain additional results regarding the characteristics of the nonlinear vibrations in the time domain. The results are in agreement with vibrations observed in recent years in many xerographic cleaning subsystems.

The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.
IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.
