Vibrations of varying frequency and amplitude are used in many technological areas to control friction. In this study we report the most comprehensive results of high precision measurements of the sli....
Brake squeal noise has been under investigation by automotive manufacturers for decades due to consistent customer complaints and high warranty costs. Sound in a squealing brake is excited by the cont....
There are several different possibilities to analyze a squealing brake system. The present paper introduces a complex measuring system which is mounted on a complete vehicle axle at a test rig. This s....
Conventional brakes commence with given brake torque distribution and abruptly change to wheel individual torque corrections when ABS-ESP intervenes. This leads to less than optimal braking, firstly a....
The importance of functional safety design has recently grown with the increasing widespread application of electric/electronic (E/E) systems in today's automotive industry. Such E/E systems, usually ....
In regenerative braking, the kinetic energy of the vehicle is stored in a battery as the electric energy that is otherwise being dissipated as heat by friction, so that the stored energy is recuperate....
The disc brake corner assembly is comprised of several subsystems (brake pad, caliper, rotor etc.) which have interfaces between two or more of these structures. The brake pad assembly as the subsyste....
The prevention of brake squeal is a significant task in brake development, because brake squeal is bothersome to users and consequently reduces a vehicle's commercial value. Due to the progress made b....
Brake lining material is one of the main factors influencing brake squeal. Actual simulation of brake squeal suffers on the missing of correct material parameters identified under conditions relevant ....
It is widely known that friction materials show a load and frequency dependent stiffness. The load dependency can be explained with a geometrical nonlinear material structure, like the existence of po....
Ceramic matrix composites (CMC) have been increasingly used as alternative materials of the rotors of friction brakes. However there is still a need for a better understanding of fundamentals of CMC r....
The friction performance of a Disc Brake Pad is even more required to present stable mu behavior in various environmental conditions such as different temperature and humidity. Interaction between com....
Metal pickup is a phenomenon that can be observed during dynamic braking with automotive disc brakes. Hard metallic particle agglomerations embedded in the friction materials rubbing surface can lead ....
Widely known is the fact that friction and wear characteristics of disk brakes are subject to pronounced temperature dependencies. For systems with organically bound brake pads, many thermally induced....
The growing awareness of health relevance of fine dust emissions beyond traditional combustion engines becomes more and more important for state of the art research activities. Already existing emissi....
