CATENARY LAB

ADMINISTRADOR DE INFR. FERROVIARIAS (ADIF)

DESCRIPTION AND GOALS OF THE ORGANISATION

The Catenary Test Bench (BECC) is a flexible installation that allows
configuring an overhead conductor rail section of 60 meters maximum, with
several combinations of geometry and different elements commonly used in
railway operations. The BECC makes it possible to study and analyze the
dynamic interaction between pantograph and catenary, considering the
three dimensions to assess the effect of wind (on the overhead contact line
and pantograph), curves, superelevations of the track, offcentring and
pantograph tilting.

AREAS OF ACTIVITY
t Modal Analysis tests
t Tests of dynamic interaction pantograph - catenary

t Closed loop tests

TEST FACILITIES, EQUIPMENT, TYPES OF TESTING AND/OR TR*"LS

The main components of the BECC are:

* Electromechanical system made up of two electrodynamic vibrators with amplifiers. It is located on a trolley for
adjustment of contact point between vibrator and catenary
* Measurement instrumentation to perform tests. Consists of two load cells to measure the force applied to the catenary
and six accelerometers placed at points where it is necessary to record the vibration
* Acquisition and control system. Includes a vibration controller, which generates the command signal to the actuator
and gets the response of accelerometers, and a control PC that interfaces between user and controller.
* Rigid catenary elements: overhead conductor rail with five spans of configurable length between 5 and 12 meters,
catenary sectioning and suspensions of types rigid cantilever, elastic cantilever or T type.

The Catenary Test Bench allows the performance of the following tests:

* Modal Analysis tests to characterize the dynamic response of different elements and configurations of rigid catenary
and pantographs, commonly used in railway operations.
* Tests of dynamic interaction between pantograph and rigid catenary in order to validate theoretical studies performed
with simulation models.
* Closed loop tests in order to reproduce and control an excitation signal on the structure both in force and acceleration.
With these tests it is possible to perform fatigue analysis and ageing of rigid catenary elements.
