Effects of braking conditions on nanoparticle emissions from passenger car friction brakes

Science of The Total Environment, 2021
Automobile friction brakes generate, in addition to coarse particles generated by mechanical processes, highly variable amount of nanoparticles from high temperature processes. The effects of braking conditions - speed, deceleration rate, brake rotor temperatures - on nanoparticle production were investigated here, aiming to provide practical guidance ...

Friction Induced Vibration: Brake Moan

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">Techniques have been developed to model friction induced vibration and these were applied to the brake moan of a vehicle. A vehicle system model and the MSC/NASTRAN solutions for geometric nonlinear and complex modes were modified by DMAP for friction input.

The Brake Rotor - Friction Partner of Brake Linings

SAE Technical Paper Series, 1990
<div class="htmlview paragraph">The brake rotor has been steadily developed since the first disc brakes were introduced in the late 50s. With the increasing demands for high performance, trouble-free brake systems, the rotor manufacturers, working closely with the automotive industry have made much progress in rotor metallurgy, design and ...

Thermal Localizations in Friction Brakes

SAE Technical Paper Series, 2008
<div class="htmlview paragraph">The determination of the heat gradients in friction brakes is precious data in the analysis of the friction brake performances. However, in calculations, the assumption of uniform contact pressure on the apparent friction surface is often retained.

Thermomechanical Analysis of Friction Brakes

SAE Technical Paper Series, 2000
<div class="htmlview paragraph">Frictional work in sliding contacts plays an important role in tribology and other related areas. Applications may be found in many engineering fields. Braking of vehicles is almost exclusively done by friction brakes, and thus, understanding of the mechanisms involved is an area of great concern when designing a ...

Friction braking type vibration damper

The Journal of the Acoustical Society of America, 1986
A vibration snubber for earthquake protection of piping including an auxiliary cylinder axially slidable in a main cylinder having a large diameter portion. The large diameter portion houses a flywheel which is secured to a rotatable center shaft. One end of the shaft is mounted in a bearing in the cylinder end.

Noise attenuated brake friction member

The Journal of the Acoustical Society of America, 1996
A method of attenuating audible sounds generated during a brake application through the engagement of a friction member (10, 30) with a rotating member. The brake is evaluated by modal and frequency response analysis to determine the natural frequencies generated during a brake application and identify the natural frequencies that create audible sounds.

Desorption of Brake Friction Materials

2023
<div class="section abstract"> <div class="htmlview paragraph">This SAE Recommended Practice specifies a method to reduce and stabilize the moisture of products containing brake friction material (disc brake pads, drum brake shoes, friction blocks) so the parts are conditioned and maintained in a stable low moisture state.</div></

Friction layers and friction films on PMC brake pads

Wear, 2004
Abstract A rather new tool, the focused ion beam (FIB) technique, was used to characterise superficial layers at micro-contact areas of a commercial brake pad. The friction material was a polymer matrix composite (PMC) with approximately 50% metal content (semi-metallic) and the counter part was a cast iron rotor.
