摘要:
［目的］悬挂式单轨交通系统具有良好的发展前景，对于其车辆过道岔的动力学性能研究目前较少，需对此进行研究。［方法］采用UM（多体动力学）软件建立车辆动力学模型，以车体最大振动加速度、走行轮最大垂向力、导向轮及稳定轮最大垂向力、车体及悬吊梁最大侧滚角为主要评价指标，针对应用于悬挂式单轨交通系统的倒T形辙叉道岔，进行悬挂式单轨车辆道岔通过性能研究。［结果及结论］倒T形辙叉道岔结构的导向轨面不平顺较大，悬挂式单轨车辆在通过曲线道岔时，很难保证导向轮的导向力不超过安全限值。针对此问题提出了一种导向轨面补偿装置。应用此导向轨面补偿装置后，悬挂式单轨车辆可以以15 km/h的速度安全通过半径为50 m的倒T形辙叉道岔，动力学性能有明显改善。

［Objective］ The suspended monorail transportation system holds promising prospects, yet researches on the dynamics performance of vehicle passing through turnouts remain relatively scarce, requiring comparison for further exploration. ［Method］ A vehicle dynamics model is established using the multi-body dynamics software UM. The main evaluation indicators include the carbody maximum vibration acceleration, the running wheel maximum vertical force, the maximum vertical force of guide and stable wheels, and the maximum lateral roll angle of carbody and suspension beam. The passing performance of suspended monorail vehicles through inverted T-shaped frog turnouts applied in the suspended monorail transportation system is studied. ［Result & Conclusion］ The structure of the inverted T-shaped frog turnouts causes significant guiding rail surface irregularity, making it difficult to ensure that the guiding force of the guide wheels does not exceed the safety limit when a suspended monorail vehicle is passing through curved segment turnouts. To solve this problem, a guiding rail surface compensation device is proposed. After applying this device, the suspended monorail vehicle can safely pass through inverted T-shaped frog turnout with a 50 m radius structure at a speed of 15 km/h, leading to a noticeable improvement in the dynamics performance.
