Abstract
The prediction method for brake linings life named “Linear Wear Hypothesis” (LWH) was developed few years ago, based an short and quick lining life tests. In line with this method, a procedure for modelling the friction properties of friction material based on the theory of the design of experiments was elaborated. This investigation made possible the derivation of mathematical models describing wear of the lining and work done by the brake as a function of braking or application conditions.
The models evaluated for a typical disc brake pad and a typical drum brake lining are explained in this article, and application of such models for prediction of the friction material life with help of the LWH, as well. Experiments realized demonstrate that combining the LWH procedure with modelling technique offers real possibilities for the prediction of lining life based on the rather short and quick tests using inertia dynamometer.
