Abstract To study the accuracy and reliability of the multi-parameter measurement results of the metrology vehicle of detecting device for overload and unbalance load, implement the dissemination of quantity values on the detecting device for overload and unbalance load of rail wagons, and ensure the consistency of quantity value, the standard detecting device for overload and unbalance load is studied and established. The uncertainty factors affecting the determination of each parameter are analyzed according to JJF 1059.1-2012 Evaluation and Expression of Uncertainty in Measurement, and the uncertainty of each parameter is evaluated by GUM method. The results show that the extended uncertainties of all parameter measurement are less than its maximum acceptable extended uncertainty.
