Modelling the wear processes of the automotive brake pad and disc
Journal Title: INCAS BULLETIN - Year 2018, Vol 10, Issue 4
Abstract
The automotive disc braking system is based on the friction between a disc and two pads and this friction determines their wear. The theoretical study proposed in this paper aims to model this wear process. It is based on a simplified geometrical model (approximation of the curvilinear trapezium with a rectangle of the same area) and considering the brake pad as a viscoelastic material, while the disc is elastic. With the help of this model we can determine the relative displacements of the pad and of the disc during the braking process. Also, when the process is stabilized, the pressure distribution can be determined. In the paper, both the relative displacements and the pressure distribution are exemplified for the inner edge, the middle and the outer edge of the brake pad.

A study of Impinging Flow on a Rotating Disc
This paper focuses on the behavior of the boundary-layer laminar flow produced by a large radius no-thickness disc which rotates inside an axial stream. Some early solutions are only known for the upstream flow field, bu...

In this presentation, we will concentrate on the vertical support, which is free from all sides. A Finite Element Model (FEM) of the IAR-93 aircraft monument has been developed in PATRAN/NASTRANĀ®, partly from a previous...
Possible Simple Structures of the Universe to Include General Relativity Effects
The general relativity describes the universe properties, the gravity playing a fundamental role. One uses a metric tensor in a Riemann space, gmiu,niu , which should be in agreement with a mass (or energy) tensor in ord...
