机车用于牵引挂车移动或提供制动力以降低列车的运行速度。电动机的电磁转矩总是通过齿轮传动系统传递到轮对，以在轮轨接触界面处产生牵引力或制动力。因此，齿轮传动系统对机车的动力传递具有重要意义。建立了考虑齿轮传动动态效应的机车-轨道垂向-纵向耦合动力学模型。该动力学模型能够考虑齿轮传动运动、车辆的竖向和纵向运动以及轨道结构的竖向振动之间的耦合相互作用。本文考虑了齿轮时变啮合刚度、非线性齿侧间隙、非线性轮轨法向接触力和蠕滑力以及钢轨垂向几何不平顺等复杂动力激励。然后，通过建立动力学模型的数值仿真和实验测试，验证了机车在牵引条件下的动力学响应。实验结果与理论计算结果吻合较好，验证了所建立的动力学模型的正确性。计算结果表明，齿轮传动系统与轮轨接触界面存在较强的动力相互作用，包括垂直运动和纵向运动，对转向架构架和车体的振动影响很小。
Locomotive is used to drag trailers to move or supply the braking forces to slow the running speed of a train. The electromagnetic torque of the motor is always transmitted by the gear transmission system to the wheelset for generation of the tractive or braking forces at the wheel–rail contact interface. Consequently, gear transmission system is significant for power delivery of a locomotive. This paper develops a comprehensive locomotive–track vertical-longitudinal coupled dynamics model with dynamic effect of gear transmissions. This dynamics model enables considering the coupling interactions between the gear transmission motion, the vertical and the longitudinal motions of the vehicle, and the vertical vibration of the track structure. In this study, some complicated dynamic excitations, such as the gear time-varying mesh stiffness, nonlinear gear tooth backlash, the nonlinear wheel–rail normal contact force and creep force, and the rail vertical geometrical irregularity, are considered. Then, the dynamic responses of the locomotive under the tractive conditions are demonstrated by numerical simulations based on the established dynamics model and by experimental test. The developed dynamics model is validated by the good agreement between the experimental and the theoretical results. The calculated results reveal that the gear transmission system has strong dynamic interactions with the wheel–rail contact interface including both the vertical and the longitudinal motions, and it has negligible effect on the vibrations of the bogie frame and carbody.
