KRAFTMESSEINRICHTUNG UND VERFAHREN ZUR BESTIMMUNG EINER KONTAKTKRAFT

摘要

The device has fiber-Bragg-grid sensors (41), each formed as an optical strain sensor and arranged at a power consuming horn (35) of a railway traction vehicle. A supply unit (43) feeds light signals with certain wavelength concentration into one of the sensors with a focal point wavelength. An evaluation unit (45) determines the measured values for a contact force between the horn and an overhead line of a catenary. An independent claim is also included for a method for determining a contact force between a power consuming horn of a railway traction vehicle and an overhead line of a catenary.
