Dynamics and Control of a High Speed Train Pantograph System
High speed trains permit faster travelling between long distance destinations, making it an easy and comfortable way of travelling. The pantograph is the element of the train that collects electrical current from the cable system above (the catenary), to the train motors. The contact force variation can cause contact losses, electric arc formations and sparking. This deteriorates the quality of...
متن کاملPantograph noise measurements in Madrid-Sevilla high speed train (AVE)
Ten years ago, the first Spanish high speed line which traveled from Madrid to Sevilla at an average speed of 250 km/h was inaugurated. At this speed pantograph noise, which is of an aerodynamic nature, is thought to have rather influence in the passengers zone. However, pantograph contribution is often omitted since main noise sources are expected to come from wheels and devices placed under t...
متن کاملPantograph Dynamics and Control of Tilting Train
The modeling methodology of tilting train is studied. The vehicle and pantograph are considered as nonlinear multiple rigid body systems, and the catenary is modeled by FEM method. The electrical mechanical actuators for carbody and pantograph tilting control are also considered in the tilting train model. The method of on-line curving detection, filtering and control is adopted for the tilting...
متن کاملStudy on Friction and Wear Properties of Pantograph Strip/Copper Contact Wire for High-Speed Train
A series of experiments on friction and wear properties of carbon strip rubbing against copper contact wire is performed on high-speed friction and wear tester with electric current. The results show that the friction coefficient is generally maintained between 0.24 and 0.37. In the absence of electric current, the coefficient of friction is higher than that in the presence of electric current....
متن کاملDirect Robust Adaptive Control of High-Speed Train Based on Nonlinear and Time-Varying Models
This paper investigates the tracking control problem of high-speed trains, and a direct robust adaptive control strategy is designed to deal with the uncertainties and time-varying properties occurring in the train dynamics. The longitudinal dynamics of the train is a typical uncertain nonlinear presentation, whose parameters, especially the coefficients of the resistance cannot be acquired pre...
