Extending Endurance for the Friction Coefficient Development of Automobile Wiper Blade

Abstract

Wiper blade is one of inexpensive automotive components, but the component is very important part considering car safety for securing automotive visual field. Therefore study for securing longer endurance of wiper blade was proceeding, that is about variables effecting on endurance. In this paper, it was proved that the effect to extend endurance could be acquired by securing proper friction coefficient. Be compared endurance in Weibull distribution that is reliability technique and seized effect about blade pressure distribution, contact pressure, blade rubber surface treatment etc. for securing proper friction coefficient. Relation between these variables was cleared through test. Also, designed and proposed tester for measuring friction coefficient of wiper blade.
