Research Development on Wiper Mechanism in Automotive Application: A Critical Review

Abstract

In this generation, usage of transportation vehicles is drastically increased. It is very important to improve the safety facility in an automobile vehicles. Due to this, many researchers have contributed to research and development on smart wind shield wiper mechanism in automotive. Considering that, the current work compiles a compilation of articles reviewed on smart wind shield wiper mechanism from year 1903 to 2015. Further than that, this work also provides information relating to the varying designs and specifications of smart windshield wiper mechanism. At the same time, the writers also propose potential future research that could be undertaken in relation to the development in wiper mechanism in automotive application, which in turn may allow for new research pathways in this area of interest. Finally, taking into consideration the design and safety factors of the current market trend wiper mechanism, the writes also propose possible windshield washing system for various application.

Determining the characteristics of contact interaction between the two-row windshield wiper and a curvilinear glass surface

“…It can fluctuate within very small limits (0.1-0.25 mm max) due to changes in the pressure of the windshield wiper on the glass, which was studied above in chapter 4.1. A y const is a variable parameter since the area A(x,t) (8) depends on the rain intensity I, which was also demonstrated in (6). In fact, A y is responsible for how much water the wiper washes in 1 pass.…”

“…Since the contact of the blade with the windshield depends on the movement of the windshield wiper, it is useful to refer to study [5], which focuses on the geometric synthesis of the mechanism of the front windshield wiper using rockers for fixing the brush. Wiper mechanisms are also studied in [6]. Despite the relevance of the topics addressed in [4][5][6], the authors do not provide data on the resulting pressure on the glass surface from the side of the windshield wiper.…”

“…Wiper mechanisms are also studied in [6]. Despite the relevance of the topics addressed in [4][5][6], the authors do not provide data on the resulting pressure on the glass surface from the side of the windshield wiper. In [7], the dynamic characteristics and mechanism of generating vibrations of a frameless windshield wiper are studied.…”

“…Taking into account the variability of the speed of the vehicle v v and the intensity of rain I during the time t rot (5), it is advisable to switch to the integral form of equation ( 6): After determining the water flow rate Q w (6), which the wiper must remove in 1 pass during t rot , we proceed to the next step -calculating the speed of water passing the profile of the rubber blade. As you know, for a round pipe where the liquid moves laminarly (in layers without turbulence), the Hagen-Poiseuille equation can be applied for a cross section with a complex configuration and a variable area along the flow axis (7):…”

“…More common is the Navier-Stokes equation, which is the basis of hydrodynamics, describing the movement of a liquid in three-dimensional space. Considering (6), for an unsteady fluid flow, the determination of the velocity v f along the windshield wiper brush (x-axis) according to the Navier-Stokes equation ( 8) can be written as follows:…”
