Preliminary experimental/numerical study for the vibration annoyance control of a windshield wiper mechanical system through a Synchronized Switch Shunt Resonator (SSSR) technology

Abstract

The present work focuses on the study and analysis of vibrations generated by the electrical motor of a wiper system on its support bracket referring to an hatchback vehicle passenger car. In the electric motor of the wiper system there can be present an imbalance transmitting vibrations to the main body via the support bracket. In this paper, after a short resume of available synchronized switch shunt damping methods, a preliminary experimental evaluation of their potential performance on noise control of the wiper system is reported. After preliminary experimental measurements of dynamic vibration by the use of vibrometer laser both on the real hatchback car then in laboratory environment, a numerical model has been created to evaluate deformations of the support bracket for comparison with the experimental data. This work realizes the preliminary numerical/experimental characterization activity to set up a new application of a control system based on a semi-active technique, called Synchronized Switch Shunt Resonator (SSSR).

Optimization on Linkage System for Vehicle Wipers by the Method of Differential Evolution

“…This optimization problem is related to another problem which we now discuss. Reducing the unpleasant rubber wiper noise on vehicle windshield has been an interesting research topic over the past few decades [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. Some simple spring-mass models for the vibration of rubber wiper were presented for simulations before [32,39,41].…”
