Abstract [en]

Dynamic behaviour and its evolution are concerns for those operating high-speed trains. In this paper, a cloud server is applied to establish a connection between the vehicle-mounted equipment and users to decrease the influence of network instability. To ensure the accuracy and consistency of data transmission, MQTT (Message Queue Telemetry Transport) protocol is used to transfer data measured from the vehicle. The paper discovers the vibration transfer characteristic and the evolution of the dynamic behaviour of several types of high-speed trains, along with wheel wear under several operation conditions, over time. The turbulence caused by high-order wheel polygonalization formed during long-term service, which cannot be weakened by the suspended system sufficiently, is harmful to the ride quality of high-speed trains. The results confirm the operational reliability of the high-speed trains in China and provide useful references for the optimisation and maintenance of high-speed trains.
