“…Other researchers have focused on the mathematical modelling and vibrational analysis of wiper blades. Goto et al 5,6 constructed an equation of motion for the vibration of a wiper blade using the cross-section of the blade and analysed the vibration generation mechanism to reduce the squeal noise. Sugita and Yabuno 7 attempted to clarify the dynamic behaviour of the wiper blade during reversal motion using both a theoretical approach and an experimental approach.…”

The structural behaviour of a windshield wiper system and the dynamic behaviour of the wiper rubber blade are investigated using finite element analysis. Non-linear contact analysis was performed to examine the influences of the structural design variables such as the curvature of the primary beam, the thickness of the yoke, the rotational angle of the yoke and the thickness of the steel beam on the distribution of the contact force along the blade length, and the effects of the vertical load and the coefficient of friction on the vibrational behaviour of the blade were investigated using transient dynamic analysis. Experimental validation was conducted by measuring the contact force distribution and the vibrational behaviour of the rubber blade. The experimental data and the simulated results show good agreement. The contact force distribution is sensitive to changes in the primary beam’s curvature, the yoke’s rotational angle and the steel beam’s thickness. The vertical load and the coefficient of friction both have significant influences on the vibrational behaviour of the rubber blade. It is found that the proper combination of the variables investigated allows a more uniform contact force distribution and less vibration and thereby improves the performance of the wiper blade. These analyses demonstrate the variables that influence the wiper blade behaviour and should provide key insight into means for improving the wiper performance.

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.

Windscreen wiper vibration problem is now becoming one of the comforts and safety concerns because it can be annoying to the driver and passengers and also affect concentration of the driver while driving. This paper investigate the problems by measuring the wiper blade contact force and vibration level on laboratory wiper experimental rig and wiper system on two different sedan passenger cars operated similarly. In order to measure the vibration and contact force along the wiper blade, MMA7660 accelerometer and a thin film force sensor FSR was used. The contact force is measured at four points; Points 1 (inner tip), 2 (middle blade) and 3 (middle blade) and Point 4 (outer tip), along the wiper blade. Based on the measurement, it was found that the contact force is much higher at Points 1, Point 2 and Point 3 compared to Point 4. For vibration level, higher vibration is occurred at Points 2 and Point 3. It can be conclude that the bigger the contact force value act on windscreen the bigger for the vibration level to be produce. From this founding, further research can be conducted and tackle the problem at certain point along the wiper blade.
