INVESTIGATION OF THE MEASUREMENT CAPABILITY OF ROLL BRAKE TESTER BY THE TEST TRAIL
Aimo Pusa, Hannu Leppälä
Abstract:
The investigation of the roll brake testers used testing for trucks has been made during year 2002. There have been developed a test trail, reported in TC-3 Congress Celle 2002. The aim of this investigation was to get information about real measurement capability of the roll brake testers used in inspection of the trucks for Finnish authority (The Finnish Vehicle Administration AKE). The usually way to calibrate roll brake tester has been to generate the reference force direct against of the force measurement transducer. This calibration does neither take in to account the mechanical construction of the rollers nor the diameters of them or the dynamic behaviour of the measurement. The investigation gives the information over practical uncertainty of the roll brake tester. The used comparing method has been static with the reference transducer as well quasistatic by the test trail, which makes the control of roll brake testers with the speed of normal use of a roll brake tester, about 3 km/h.
