Abstract: In order to explore the influence of track irregularity on the gear transmission system of urban rail transit vehicles, we built the Metro helical gears model of the bend-torsion-axes, which considered the time-varying meshing stiffness, gear meshing error, backlash nonlinearity etc. Besides, the track spectrum excitation was considered in the system for the first time, used the variable step forth order Runge-Kutta algorithm solve the model, obtained the gear system dynamic response diagrams, analysed the system stability and dynamic transfer error (DTE) of the gear system under the track spectrum excitation with the dynamic model and the ADAMS simulation. The result show that the single periodic motion of the system is changed into the quasi periodic motion with the influence of track spectrum excitation, and the DTE was increased. The paper lays a theoretical foundation for the research of the Metro gear transmission system. [Received 16 July 2016; Revised 27 October 2016; Accepted 16 November 2016]
