In this paper,the working principle and structure of the dynamic simulation device for track geometry parameters are introduced,and the simulation data are analyzed.The feasibility was evaluated by comparing with the data from the traditional test station.The accuracy of the simulator is analyzed and the uncertainty evaluation is carried out by taking the traceability detection of the track inspection instrument as an example.At the same time,the current status of traceability technology of track detection instruments is studied to improve the accuracy of mag-nitude traceability.
