Abstract
A measuring system for measuring the elasticity of an overhead line of a track includes a non-contacting sensor for detecting the position of a measuring point of the overhead line and an evaluation device for calculating the elasticity. A mechanical excitation device sets the overhead line into vibration through active excitation. The sensor is set up to detect a vibration progression and the evaluation device is set up to derive mechanical properties of the overhead line from the vibration progression. The mechanical properties, such as the elasticity of the overhead line, are derived from characteristics of the corresponding vibration curves in the evaluation device. A method for measuring the elasticity of an overhead line of a track and a track construction vehicle are also provided.
