4. 2. Brake Judder

   Author : Helena Jakobsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Brake judder is a braking induced, forced vibration occurring in different types of vehicles. The frequency can be as high as 500 Hz, but usually remains below 100 Hz and often as low as 10-20 Hz. The driver experiences judder as vibrations in the steering wheel, brake pedal and floor.

5. 3. Thermomechanical behaviour of tread braked wheels

   Author : Eric Landström Voortman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical analysis; high temperature testing; thermal analysis; full-scale brake rig testing; tread braking; Railway wheels; finite element analysis;

   Abstract : Tread brakes, also known as block brakes, are a type of friction brakes commonly used in the railway industry. They are a low-cost and low-maintenance solution compared to more complicated systems such as disc brakes or electrodynamic brakes. READ MORE

6. 4. Drum Brake Squeal

   Author : Johan Hultén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction induced; squeak; vibration; drum brake; squeal; instability; self-excited; noise;

   Abstract : Drum brake squeal is a common discomfort. The main goal of this thesis is to investigate the mechanisms that generate drum brake squeal and to create a base for the search for solutions. A series of steps towards the understanding of these mechanisms are taken. Firstly, a simple model for friction-induced vibration is presented. READ MORE

7. 5. On improvement of cast iron brake discs for heavy vehicles

   Author : Gael le Gigan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brake disc; cast iron; hot spots; cracking; elevated temperatures; material modelling; finite element analysis; drag braking; material testing; rig experiment; fatigue assessment;

   Abstract : Disc brakes are commonly used in motorcycles, passenger cars, commercial vehicles, heavy-duty vehicles, passenger trains and landing gears of airplanes. Depending on the application, a wide variety of brake discs have been developed, with a multitude of designs, geometries and materials. READ MORE
