A novel method for attenuation of brake judder directly at the source is proposed, utilizing an electromechanical brake to actively compensate for the variation in brake torque that causes judder. Tak....
Brake squeal of the light vehicle disc brakes have been the subject of numerous studies in the last thirty years. Several analytical and numerical models as well as dynamometer and vehicle test proced....
Contact pressure distribution is one of the key influence factors and the essential causes of brake squeal. In this study, a drum brake finite element model is established using ABAQUS. The contact pr....
This paper examines the onset of brake noise and the mechanisms involved during the initial stages of noise occurrence. The emphasis is directed towards disc mode coupling and improvements are suggest....
Squeal of disc brakes is considered as a main source of discomfort for passengers. Typically 1 to 4 kHz noise is considered low frequency squeal and ≻8 kHz noise is considered high frequency squeal. I....
Many papers of brake noise research were presented before. Today it is required in brake design stage to predict the influences of countermeasure for every brake noise. For example, moan noise is some....
Brake squeal is a phenomenon of self-induced vibration of the brake components during braking. There are many kinds of brake squeal cases whose mechanisms require acting on a various number of potenti....
This paper deals with creep groan noise in vehicles which is a low frequency vibration problem at 20∼500Hz that appears in low brake pressures and extremely low speed especially in automatic transmiss....
Brake squeal has been and remains a challenging issue to vehicle manufacturers due to its complicated interaction between structural dynamics and tribological aspects. A significant number of studies ....
In this paper, vibrations caused by brake judder are investigated theoretically and experimentally, in a vehicle. The experimental results of a road test are compared with the theoretical results obta....
It is necessary to consider both pad stiffness in static and dynamic situations to develop brake pads that create effective braking and squeal less. Brake pads that have a high degree of static stiffn....
The prevention of brake squeal in disc brakes is an important concern in designing a brake system because, in terms of quietness, brake squeal reduces a car's commercial value. Over the past years, ma....
The goal of constructing squeal free brakes is still difficult to achieve for design engineers. There are many measures that are beneficial to avoid or decrease brake squeal, examples are the increase....
The effects of pad properties and thermal coning of discs on high speed judder were investigated using dynamometer and vehicle tests. The friction materials of different thermal conductivities were ma....
