Abstract Aiming at vibration problems of a locomotive driving system, its dynamic model and corresponding equations under internal gears meshing dynamic excitation and external wheel-rail adhesion excitation were established considering static transmission error, time-varying mesh stiffness and backlash due to inside gears meshing. The main resonance frequency equation of the system was derived using the multi-scale method. Case studies were done. The influences of the system’s parameters on its frequency response curve were analyzed. The effects of wheel-rail adhesion force changes on the system’s main resonance time domain response were simulated. The results showed that dynamic changes of wheel-rail adhesion force can affect the system’s main resonance frequency and amplitude; the nonlinear characteristics of the system can lead to multi-value phenomena of the main resonance’s frequency response curve; decrease in the coefficient of error velocity term F3, the amplitude of error harmonic term er, and the ratio of the first harmonic stiffness ke1 or increase in the system’s damping can reduce multi-value regions; meanwhile, decrease in F3,er and ke1 can suppress the main resonance amplitude to a certain extent; when the main resonance occurs not considering gears mesh damping within the dimensionless time range of 2000~2500 and the creep rate at static equilibrium position s0 = 0.012, the maximum displacement considering dynamic change of wheel-rail adhesion force decreases by about 35.35% compared with that considering constant wheel-rail adhesion force; when s0 is 0.035, the maximum displacement considering dynamic change of wheel-rail adhesion force increases by about 115.55% compared with that considering constant wheel-rail adhesion force; in the above two cases, considering dynamic change of wheel-rail adhesion force or not can greatly affect frequency spectrum and phase trajectory of the system’s vibration.
