Braking forces occurring during emergency brake applications of passenger trains are generated by disc units. The acting friction depend on the frictional properties between and pad influenced relative velocity, temperatures normal pressure contacting surfaces. In this work a mathematical model is developed which aims to link these influencing variables instantaneous coefficient in order includ...

The most important machine elements of the braking system are brake disc and pads. During process, torque is necessary to decelerate speed vehicle or stop it. High amount frictional heat will be generated during process due sliding between moving part (brake disc) fixed parts pads). present research involves two parts, in first it investigated effects difeeerent properties three friction materi...

Replacing high-strength frictional materials with lightweight composite alternatives is currently a global challenge for researchers. In this work, aluminum alloy (AA2900)-based metal-matrix composites reinforced 6 wt.% α-alumina were fabricated then subjected to T6 heat treatment followed by case hardening. The resulting samples exhibited improved hardness, strength behavior, and stress–strain...

In the braking system, heat dissipation generated by friction between disc and pad should be evacuated as quickly possible. this work, five common different automotive brakes were studied through mathematical theories of transfer numerical methods using ANSYS software. addition, a direct comparison experimental, theoretical, simulation values found in open literature was performed to propose br...
