摘要

摘要: 建立了考虑完整牵引传动系统的车辆动力学模型，在传动系统建模时分别采用人字齿轮和斜齿轮；对比分析了2种齿轮传动系统对轮轨接触参数、车辆动力学性能的影响；分析了传动系统中人字齿轮啮合对车轮磨耗的影响。分析结果表明：人字齿轮增加了齿轮副啮合刚度，从而使扭矩传递更加平稳；人字齿轮能有效减少车轮与钢轨的横向作用和轮对横向位移，2种模型在牵引过程中的最大横向位移分别为8.9和5.7 mm，人字齿啮合模型减小了35.9%；人字齿轮有效减小了齿轮的轴向力，斜齿和人字齿轮轴向力最大值分别为4.50、2.85 kN；在高速动车组使用人字齿轮传动系统时，新车轮与新钢轨匹配后，车轮的磨耗相对集中，不利于车轮型面的均匀性磨耗；直线工况下，人字齿轮啮合模型的车轮磨耗较斜齿轮啮合模型增大5.96%；牵引力矩对车轮磨耗影响较大，谐波力矩对车轮磨耗有一定影响，增加谐波力矩会增加车轮磨耗，螺旋角对车轮磨耗影响较小。研究为高速动车组人字齿轮啮合传动系统的设计提供了相关依据。

Abstract: A vehicle dynamics model incorporating the complete traction transmission system was built. Herringbone and helical gears were adopted in modeling the transmission system. A comparative analysis was conducted on the influence of the two gear transmission systems on wheel-rail contact parameters and vehicle dynamics performance. The effect of herringbone gear meshing on wheel wear in the transmission system was analyzed. Analysis results show that herringbone gears increase the meshing stiffness of the gear pairs, resulting in smoother torque transmission. Herringbone gears effectively reduce both the lateral forces between wheels and rails and the lateral displacement of wheelsets. The maximum lateral displacements during traction were 8.9 and 5.7 mm in the helical and herringbone gear models, respectively, indicating a reduction of 35.9% in the herringbone gear model. Herringbone gears significantly reduces the axial forces in the gears, with the maximum axial forces of helical and herringbone gears reaching 4.50 and 2.85 kN, respectively. When herringbone gear transmission systems are applied in high-speed EMUs, wheel wear becomes more concentrated after new wheels are paired with new rails, which make it difficult to achieve uniform wheel profile wear. Under straight-line conditions, wheel wear in the herringbone gear model increases by 5.96% compared to the helical gear model. Wheel wear is strongly affected by the traction torque. Harmonic torque affects wheel wear to some extent, and its increase lead to higher wear. The helix angle has a minor effect on wheel wear. The research provides a theoretical basis for the design of herringbone gear transmission systems in high-speed EMUs.
