In this study, different disc brakes and friction materials are evaluated with respect to particle emission output characteristic features derived. The measurements take place on an inertia dynamometer using a constant volume sampling system. Brake wear factors of concepts in sizes determined compared, grey cast iron disc, tungsten carbide-coated carbon ceramic disc. were tested over section (t...

In this paper an e cient sequential approach for simulating thermal stresses in brake discs for repeated braking is presented. First a frictional heat analysis is performed by using an Eulerian formulation of the disc. Then, by using the temperature history from the rst step of the sequence, a plasticity analysis with temperature dependent material data is performed in order to determine the co...

In electromechanical brakes, central controllers require accurate information about the clamp force between brake pad and disc as a function of pad displacement. This function is usually denoted as characteristic curve of the caliper. In a typical electromechanical braking system, clamp force measurements vary with actuator displacements in a hysteretic manner. Due to ageing, temperature and ot...

Cu-based friction materials have better tribological properties, high mechanical strength, and excellent thermal conductivity; therefore, they are widely used as in high-speed rail brake systems. However, with the remarkable increase running speed of trains, a great amount energy temperature induced system; new challenges generated for pad materials. In this paper, were prepared addition variou...

One of the crucial components brake system is pads. Due to its importance in sector, researchers have carried out many recent studies on this subject. In study, two different pad samples were developed from alumina material and micronized quartz as friction modifiers. Samples containing 12% produced by hot molding method. The coefficient wear rates established tester order assess performance cr...

introduction: knee orthosis is used in different cases and can be seen pistoning movement in all orthosis. the purpose of this study was to evaluate the effects of increasing mass knee brace and two kinds of silicon and polyethylene (pe) pad on pistoning movement during walking, on health subject. material and methods: a total of 20 healthy volunteers, including 10 men and 10 women, with an ave...

For the sake of high-efficiency energy recycling and brake security for series-parallel hybrid electric vehicle, an integrated brake system with an electric consuming brake subsystem and advanced strategy is proposed. The specific structure of electric consuming brake subsystem is introduced. The brake processes in different brake conditions are analyzed. A brake control strategy relying on the...
