The brake system is one of the most important systems on the vehicle, especially from the
aspect of traffic safety. The use of the braking system comes with many undesirable effects …

The friction block height of high-speed trains decreases with service time. However, the
influence of height on friction-induced vibration and noise (FIVN) is unclear. Therefore, we …

A tribology test was carried out on a test device to simulate the braking performance of a
high-speed train and investigate the effect of the friction block's residual height on friction …

Drag brake experiments using hexagonal, pentagonal, and circular friction blocks are
conducted using a self-designed small-scale brake dynamometer to investigate the …

Uneven wear is an inevitable wear phenomenon in the braking system of high-speed trains.
To avoid the hidden dangers of the aggravation of uneven wear to the safe operation of …

In this study, the effects of granularity and proportion of CrFe on both braking performance
and dynamic characteristics of copper-based friction materials were investigated. Braking …

In this study, a three-degree-of-freedom dynamic model of a disc brake system for a high-
speed train is established by considering disc− pad nonlinear friction, wheel− rail adhesion …

This study investigates the effects of interfacial wear characteristics on stick-slip vibration
under different normal loads. The results reveal that the amplitude and frequency of stick-slip …

A piezoelectric cantilever vibration energy collector (PCVEC) was developed to harvest
friction-induced vibration (FIV) energy. Tests were conducted using a CETR machine. A …

The dynamic performance of the trailer bogie brake system is essential for the safe operation
of a high-speed train during the braking process. In this work, we developed a novel ten …
