Abstract  

In order to comprehensively analyze the influence mechanism of track irregularity and wheel-rail profile compatibility on metro vehicle sway, a combination of dynamic test and numerical simulation was used to study. The lateral vibration acceleration of swaying vehicle, wheel-rail profile and track irregularity were tested. The characteristics of vehicle sway and differences in wheel-rail profile compatibility were revealed. The influence of track irregularity and wheel-rail profile compatibility on vehicle sway were analyzed. Results show that the ride quality will be seriously affected when there is periodic irregularity on the metro operation lines. The difference in the proximity of bogie hunting frequency due to wheel-rail profile compatibility, track excitation frequency and carbody sway modal frequency is the cause of the difference of vehicle ride quality. Measures should be taken in time to treat periodic irregularities on the lines. Meanwhile, reasonable control of the equivalent conicity of wheel-rail profile compatibility can effectively improve the running quality of metro vehicle.

轨道不平顺与轮轨匹配对地铁车辆晃动的影响

为了综合分析轨道不平顺与轮轨匹配对地铁车辆晃动的影响机理,采用动力学试验与数值仿真相结合的方法展开研究. 测试车辆晃动的横向振动加速度、轮轨廓形及轨道不平顺,掌握车辆晃动、不同轮轨匹配特征,分析轨道不平顺及轮轨匹配对车辆晃动的影响. 结果表明:当地铁运行线路存在周期性轨道不平顺时,将严重影响车辆平稳性;不同轮轨型面匹配引起的转向架蛇行运动频率与轨道激励频率、车体滚摆模态频率的接近程度不同,是导致车辆平稳性存在差异的原因. 及时处理轨道周期性不平顺,合理控制轮轨型面匹配的等效锥度能够有效改善地铁车辆的运行品质.
