Active control of pantograph vertical vibration of tilting train;

Study on mode selection of tilting mechanisms for tilting train;

The principles and the characters of actuators of tilting trains at present are introduced in this paper.

Besides modern high-performance locomotives, tilting trains, low-floor vehicles and passenger coaches there are several elder classes which have been upgraded in the meantime.

Based on a recently developed approach to fault detection and diagnosis for sensors,this paper employs it in the research of tilting trains.

Experimental and theoretical study on natural circulation flow under rolling motion condition;

Based on the visual observation and the analysis of experimental data,it was found that flow patterns with rolling motion were different from that of steady condition.

The study was designed to investigate the effects of rolling motion on the motion of gas bubbles,dispersed bubble flow and liquid film thicknesses for annular flow.
