2、 study of wiper shape for the uniformed pressure on the glassModeling & Analysis VariablesExperimental Details The wiper secure a drivers sight about 80% of windshield.ConclusionResultsv We focused on uniformed pressure which is very important thing for well polished condition. This study was ap

3、proached by changing shape. So, primary curvature was changed and three type of results was got by changing yoke angle, yoke thickness and rail spring thickness.v The conclusion is that in flat type wiper included yokes case, Yoke angle is sensitive shape parameter and Yoke thickness can reduce Yoke

4、 angles sensitivity.v This study was limited in case of flat type wiper included yokes; however this study will be approached another type wiper.PartYoungs modulus (GPa)Poissons RatioMooney-Rivlin parameters (C10,C01)PrimarySpringYokeRubber210210210-0.30.30.30.499-(3.1071E5, 5.2202E5) The uniformed

5、pressure is very important characteristic for well polished condition.Therefore, the study of wiper shape for the uniformed pressure is necessary for drivers safety Piezo-resistance Pressure sensor device (Tekscan co.)We measured the weight (g/mm) using Tekscan device for three samples. We use three

6、 kinds of primary curvatures for yoke angle, yoke thickness and rail spring thickness. Each result was obtained from Y-normal stress at end of rubber which is in contact with the glass.

Additionally, we changed yoke thickness and rail spring thickness.v Even though we changed small angle

10、of about 1 that can be easily occurred in manufacturing line, the curve of wiper contact pressure changed a lot.v The contact pressure also can be changed by different yoke thickness.v Rail spring thickness variable is not important for uniformed pressure.Yoke angle was changed for dividing weight at each yokes end point, and then used for yoke and rail spring thicknessWhen thickness became thicker, one yokes end point weight :which was added weight above
