ABSTRACT: For monospaced automotives (MPV), windshield surface is large, which requires that for a

good visibility, the “cleaned” windshield surface to be as large as possible, meaning the driven

components trajectory (windscreen wiper arms) of the wiper mechanism to be well adapted to the

windscreen surface. This paper presents component and functioning of the windshield wiper on

Renault Scenic automotive. Analysis and dynamic simulation was achieved in 3D Autodesk Inventor

Professional modeling and design, considering that the mechanism is a multibody system (mbs). At the

same time it was made finite element method analysis to the mechanism main rod, by isolating her

from the rest of the mechanism in a moment of time where the loading mechanism is maxim.

KEYWORDS: windshield wiper, mechanism, dynamic simulation, connecting road

INTRODUCTION

For monospaced automotives (MPV), windshield surface is large (≈ 1,4 m2), which requires that

for a good visibility, the “cleaned” windshield surface to be as large as possible, meaning the driven

components trajectory (windscreen wiper arms) of the wiper mechanism to be well adapted to the

windscreen surface.

Windshield wiper mechanism arrangement from road vehicles is shown in figure 1.

wiper mechanisms

In practice there are a wide variety of constructive solutions for windshield wiper mechanisms on

road vehicles, the most common being based on articulated parallelogram or anti articulated

parallelogram mechanisms as shown in figure 2.
