A real-time weighing of trains using rail weighbridges (RW) is required for safety reasons. Therefore, RW performance is critical and can be obtained from the calibration result. A study on the feasibility of more efficient rail weighbridges calibration method using force transducers has been carried out. The purpose is to overcome the difficulty of using a big capacity of reference dead weight in the location of rail-weighbridges as in the conventional method. A traceable force transducer with a relative standard uncertainty of 0.02 % (according to the ISO 376 calibration method) is used for the study cases. The calibration is carried out by comparing the weight measurement of the loader (wagon and masses load) using rail-weighbridges (as the unit under test) and force transducers (as the reference) in static mode. The uncertainty evaluation of the acceleration of gravity and air buoyancy at the location is around 50 ppm. Based on the simulation using typical data, the calculation result meets the relative expanded uncertainty is 0.32 %. These results indicate that the method complies with the technical requirements of OIML R 106-1 class 2 and practically be easier. [ABSTRACT FROM AUTHOR] |
