A ridge in a time-frequency graph (TFG) describes the relationship of signal component's instantaneous frequencies over time. Accurate extraction from TFGs is beneficial for assessing machine health conditions without rotational speed measurement. This article proposes new automated and adaptive (AARE) method. The AARE develops an edge detection strategy to avoid excessive interferences when searching ridge. Besides, creates balance between exploring peak amplitudes guaranteeing continuous...
A gear transmission system is a key element in locomotive for the of traction or braking forces between motor and wheel–rail interface. Its dynamic performance has direct effect on operational reliability its components. This paper proposes comprehensive locomotive–track coupled vertical dynamics model, which driven by axle-hung motors. In this interactions other components, e.g. wheelset, are considered based detailed analysis structural properties working mechanism. Thus, mechanical power...
Traction or braking operations are usually applied to trains locomotives for acceleration, speed adjustment, and stopping. During these operations, gear transmission equipment plays a very significant role in the delivery of traction electrical power. Failures transmissions likely cause power loses even threaten operation safety train. Its dynamic performance is closely related normal service entire train, especially under some emergency conditions. In this paper, locomotive–track coupled...
Development of railway transportation capabilities towards high-power, high-speed and heavy axle-load makes the dynamic interactions between electric drive subsystem mechanical a locomotive more intensive complicated, which may threaten operational safety. However, included dynamics mechanism influencing law have not been revealed completely. Based on co-simulation method vehicle-track coupling dynamics, model enables considering through an electromagnetic interface motor control is...
