Chatter is one of the unwanted noises generated during wiper operation. It is a low frequency and selfexcited vibration that is often generated before and after the wiper reverses direction. This leads to poor visibility and an annoying sound to the driver and passengers. This paper intends to propose a control technique that is capable of reducing chatter noise and vibration in the automotive windshield wiper system. In doing so, an existing two-dimensional mathematical model of a wiper system is adopted. MATLAB Simulink is then used to simulate vibration response of the wiper. The simulated results are then verified by those obtained in the experiment. With the verified model, a control strategy, namely, input shaping is introduced. It is found that input shaping technique can reduce vibration level by approximately 30 percents over the model without control scheme.

“…1) comprises an electric motor and a linkage mechanism which converts the rotational movement of the motor into the back and forth motion of the wiper arms [17]. The mechanical structure of the wiper blades, which is attached to the arm tips, holds the rubber blade which drains the water off the windshield [6] and [10].…”

Flexible Wiper System Dynamic Instabilities: Modelling and Experimental Validation

et al. 2007

The optimization of wiper systems under various conditions and the creation of a product which is as robust as possible are the main objectives for an equipment supplier. However, in certain conditions, instabilities can appear and generate wiping defects due to the rubber-glass contact. To improve wiping quality and to reduce the number of test stages for design, this study proposes a wiper system modeling method. The wiper system is represented by a rigid blade holder on which a rubber blade is fitted. This rigid blade system is used on a flat test bench at constant wiping velocity. The model is based on modal synthesis methods and will be validated through comparison with experimental tests under various conditions. The right correlation obtained allows the same modelling method to be applied to the new generation of flexible wiper blades which take account of the degree of freedom of the wiper blade flexions. So, a new computation tool will be developed and validated through experimentation on a specific test bench.

“…Okura et al [3] performed dynamic analysis of blade reversal behaviour using a 2-dimensional (2D) mechanical model of a wiper system and a spring-mass model of an arm and blade. They, in another work, further studied the dynamic analysis using a complete 3dimensional (3D) model.…”

This paper presents an approach to predict automotive windscreen wiper chatter noise using the finite element method. In this study, a 3-dimensional finite element model of a real wiper blade is developed and then validated using experimental modal analysis. In order to assess stability of the wiper blade assembly, complex eigenvalue analysis is performed using ABAQUS. The positive real parts of a complex eigenvalue indicate an unstable system. The baseline model is first simulated and stability of the system is examined. Having found a predicted unstable frequency that generates chatter noise, various structural modifications are proposed in order to reduce the vibration.
