On Friction Braking Demand with Regenerative Braking

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">Developments in Hybrid Electric and pure Electric Vehicles are intended to improve the operational efficiency of road vehicles. Regenerative braking, which has long been established in rail vehicles, is integral to efficiency improvement, with up to 30% of overall traction energy demand satisfied by energy saved ...

Friction characteristics of a brake friction material under different braking conditions

Materials & Design (1980-2015), 2013
Abstract As the evaluation of the tribological properties of the brake lining material is important for the braking performance identification, a pad-on-disc friction and wear tests of a commercial brake pad material against cast iron disc were conducted under low, middle and severe conditions. Three experiments via (t1), (t2) and (t3) with different

Friction Induced Brake Vibrations

Volume 6B: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract This paper deals with friction induced brake vibrations showing frequencies above 1 kHz and a narrow bandwidth. This phenomenon is usually called ‘brake squeal’. After analyzing squeal excitation mechanisms, a rigid body brake model displaying the main features of a floating caliper disc brake is presented.

Friction mechanism in industrial brakes

Wear, 2001
Mechanical brakes are acting not stochastically but surprisingly determined as the presented results measured on industrial brake systems will show. They help understanding these complex friction systems. An important mechanism is thereby the periodically change of the local friction intensity during the continuous friction process.
