Abstract: Track inspection system employs the technologies such as six degrees of freedom STEWART platform to simulate multidimen-sional motion of bogie and a four-channel electric servo platform analog vertical and lateral horizontal movement of the two tracks. This ar-ticle discusses the mathematical modeling of the STEWART platform, and to establish mechanisms for coordination and synchronization control track four-channel analog platform. The development of control systems software that enables synchronous motion control of six de-grees of freedom inspection beams and track platform, which can simulate actual movement of track detection beam and track in the labora-tory. It provides a means to simulate actual working conditions in the laboratory for a variety of on-board track inspection equipment.
