Recently, new brake pads have been developed using sustainable materials that are not harmful to the environment. In this study, effect of blue-colored Cupressus arizonica cones was determined as a friction modifier in pad composites. Four different samples were prepared by grinding cone material. The samples’ physical and chemical properties performances compared, finally, their microscopic an...

In this paper, an experimental analysis performed on a simplified brake apparatus is presented. Brake squeal is a major concern in braking design. During past years a common approach for squeal prediction was the complex eigenvalues analysis. Squeal phenomenon is treated like a dynamic instability. When two modes of the brake system couple at the same frequency, one of them becomes unstable lea...

Abstract Brake systems are essential for the speed regulation or braking of a high-speed train. The vehicle dynamic performance under condition is complex and directly affects reliability running safety. To reveal behaviour in process, comprehensive trailer car dynamics model (TCDM) considering brake established this paper. interactions between system other connected components achieved using d...

Brake noise, especially brake squeal, has been a subject of intensive research both in industry and academia for several decades. Nevertheless, the state art simulations does not provide predictive tool, extensive experimental investigations are still necessary to find an appropriate design. Actual focus on consideration nonlinearities which fact essential this phenomenon. Unfortunately, by far...

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...
