Modeling and Simulation of Acting Force on a Flexible Automotive Wiper

Ismasyariff Salleh, M. Z. Md Zain, A. R. Abu Bakar

Abstract

A vehicle wiper system has a potential to generate noise and vibration during its operation. These unwanted dynamics provide poor visibility to drivers and passengers especially during raining condition. It can also bring annoy to them while the wiper continuously sweeping the windscreen. This paper focuses on the development of a simulation model for a wiper system based on the mathematical expression using the Newtonian method. The model is compared with the previous model based on a numerical method to verify the developed analytical approach. A parametric analysis is then conducted to examine behavior of the dynamic system when the parameters are varying. Two acting forces of different speed levels to run the wiper blade are applied to the model and the levels of noise and vibration for the model are compared both in time and frequency domain.

Keywords
