摘要:
［目的］悬挂式单轨车辆在运行时受轨道梁影响，容易产生横摆运动。横摆运动对车辆的平稳性会产生极大影响，因此有必要对横摆运动发生的原因进行分析，进而找到解决车辆横摆的办法，提高乘车舒适性。［方法］分析了悬挂式单轨车辆结构，找出了影响车辆运行平稳性的主要因素以及对车辆横摆运动影响最大的因素。依托上海宝山悬挂式单轨试验线进行试验验证，采用精密仪器测量了车辆平稳性指标、车厢横向晃动指标及车厢横向振动加速度，结合轨道梁试验数据，对测试数据进行筛选并进行了对比分析，最后确定了对车辆横摆运动影响最大的因素。［结果及结论］轨道梁内侧壁尺寸是引起车辆转向架产生横摆运动的主要原因。横摆运动对车辆平稳性影响最大，但无法完全解决，需要从设计上提高轨道梁的制造精度来匹配导向轮的尺寸，并在制造过程中要严格控制轨道梁和转向架的尺寸。
Abstracts:
［Objective］ Influenced by the track beam, the suspended monorail vehicle is prone to yaw motion during running, which significantly affects the vehicle′s stability. Therefore, it is necessary to analyze the causes of the yaw motion to find out the solution and improve the ride comfort. ［Method］ The structure of suspended monorail vehicle is analyzed. The main factors that affect the stability of the vehicle running and the greatest influencing factor on the vehicle yaw motion are identified. Verification tests are conducted on Shanghai Baoshan suspended monorail test line. Precision instruments are used to measure the stability index of the vehicle, the lateral shaking index and the lateral vibration acceleration of the carriage. The test data are screened, compared and analyzed in combination with the test data of the track beam. Finally, the greatest influencing factor on the vehicle yaw motion is determined. ［Result & Conclusion］ The dimension of the inner wall of the track beam is the main cause for the yaw motion of the vehicle bogie. The yaw motion has the greatest impact on the vehicle stability, but can not be completely solved. It is necessary to improve the manufacturing precision of the track beam through design to match the dimension of the guiding wheel, and strictly control the dimensions of the track beam and the bogie in the process of manufacturing.
