Research on the distribution of aerodynamic noises of high-speed trains... Pantograph head, junction of upper arm and lower arm, and chassis region were main aerodynamic noise sources of pantograph....
Numerical computation and optimization design of pantograph aerodynamic noise... It is presented from the result that the values of the pantograph head, push rod and base are relatively large, mainly because rather prominent structures and more parts in these areas have some interference on the flow field....
Intelligent condition monitoring of railway catenary systems: a bayesian network approach... It combines five types of measurements related to catenary condition, namely the contact wire stagger, contact wire height, pantograph head displacement, pantograph head vertical acceleration and pantograph-catenary contact force, as inputsbased on their physical meanings and correlations....
Identification of the catenary structure wavelength using pantograph head acceleration measurementsFor the condition monitoring of railway catenaries, the potential utilization of pantograph head (pan-head) vertical acceleration instead of pantograph-catenary contact force is discussed in this paper....
