Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The braking is very important from the aspect of traffic safety. During the braking process, due to the pressure action between the brake disc and brake pads, it comes an increment in the friction force, which as the consequence, results in heat generation and the wear of the friction couple. In this research, the results obtained experimentally (braking time, decrement of the speed of the simulated vehicle, the braking pressure, and the friction coefficient) were used, as the input for the numerical analysis, with the aim of determining the wear of brake pads. The obtained results show that the greatest wear intensity is in the case of the greatest braking pressure (5 MPa). However, the greatest wear amount was obtained for the case when the braking pressure was 4 MPa.
