Excessive vibrations of railway vehicles induced by dynamic impact loadings have a
significant impact on train operating safety and stability; however, due to the complexity and …

Disturbance observer-based sliding mode control (SMC) on the active vertical suspension
(AVS) is developed to suppress the car body's rigid and flexible vibration to improve ride …

The effect of dynamic unbalance of the underframe suspended rotational equipment on the
flexible vibrations of the carbody has become a major concern for high-speed trains. It is …

This paper examines the influence of the equipment considered as a DVA (Dynamic
Vibration Absorber) upon the mode of vertical vibrations of the car body in high-speed …

The resonance vibration of flexible car-bodies greatly affects the dynamics performances of
high-speed trains. In this paper, we report a three-dimensional train–track model to capture …

To study the effect of car body-mounted equipment on the car body flexible vibration, a
vertical rigid-flexible coupling model of a high-speed vehicle is established, which includes …

Considering the coupling vibration of a flexible carbody and the underneath suspended
equipment, a vertical coupled vibration model of a high-speed train was constructed. A roller …

The coupled system of the car body and the under-chassis equipment is a significant part of
the railway vehicle and directly influences the vehicle dynamics. A continuous modal …

This study aims to effectively and robustly suppress the low-frequency vibrations of floating
slab tracks (FSTs) using dynamic vibration absorbers (DVAs). First, the optimal locations …

Carbody vibration control and ride comfort improvement are important research parts of high-
speed railway vehicle dynamic. The effectiveness of utilizing carbody underframe …
