“…Some measures for improving the wiperwindscreen system were proposed according to the vibration and noise results predicted under different rotational speeds and friction conditions. However, the literatures [16][17][18][19] did not consider that the dry and wet conditions in the actual operating situations of the wiper blade need to be analyzed by different friction theoretical models. The 2DOFs model built by Unno et al 20 considered the influence of static and static friction, and calculated the transition time based on relaxation variable method.…”

This paper is concerned with the friction and vibration characteristics of a vehicle wiper-windscreen contact. The dynamics and friction models of the wiper-windscreen system are established to study the frictional vibration and noise of the wiper-windscreen system. The dynamic model of the wiper-windscreen system is established and the analytical formulas are derived. Based on the negative slope formula of friction coefficient with respect to relative velocity, the Coulomb’s friction law, and the fluid lubrication characteristics, the friction models of the system are built in dry and wet operating conditions, respectively. Meanwhile, the formulas of friction coefficient and relative velocity in time domain are presented. The changes of blade angle and friction with time in different working conditions are investigated. The Runge-Kutta method is used to analyze the nonlinear dynamic response and friction characteristics of the friction models. The simulations successfully reproduce the vibrations of the wiper blade in actual motion. The effectiveness of the dynamic model and the friction models is verified by comparing the simulation results under different working conditions. The dynamics and friction models presented in this paper can provide theoretical references for structural optimization of the wiper blade, and thereby the vibration and noise control of the wiper-windscreen system.

Automotive wiper-windshield friction noise is one of the important factors affecting the vehicle interior sound quality. Due to its transient, nonlinear, and uncertain characteristics, the wiper-windshield friction noise has always been a problem in vehicle engineering. Based on rigid-flexible and acoustic-structure coupling models, a hybrid simulation procedure for the friction-induced vibration and noise of a wiper-windshield system is presented in this paper. In light of the rigid-flexible coupled dynamic equations and acoustic-structure coupled automatic matched layer (AML) based on the finite element method (FEM), the software ANSYS Workbench and LMS Virtual. lab. is selected and used for modeling and simulating the frictional vibration and noise of the system under different working speeds and lubricating conditions. In the friction noise simulations, the calculated vibrational responses from the ANSYS are input into the LMS as the excitations of a virtual sound field in a vehicle cavity. Experimental verifications suggest that the proposed hybrid approach is effective and feasible for frictional vibration and noise simulation of the wiper-windshield system. The work done in this paper may provide theoretical and technical supports for acoustic design of wiper-windshield systems, and has guiding significance for interior sound-quality optimization and control of vehicles.
