摘要:
借鉴轨道交通车辆差速控制技术，在跨坐式单轨车辆走行系统上增设差速机构，可使左、右走行轮以不同转速通过曲线，从而达到改善车辆动力学性能、降低走行轮磨损的目的。 建立了带差速机构的跨坐式单轨车辆耦合动力学模型。与常规单轨车辆相比，带差速机构跨坐式单轨车辆在曲线工况下走行轮的纵向力、回正力矩降幅明显，车辆动力学性能更优，车辆走行轮磨损也得到有效控制。
Abstracts:
Relying on urban rail transit vehicle differential control technology，differential mechanism is installed on vehicle running system，which makes the left and right running wheels passing through curves at different speeds，thus the goal of improving the vehicle dynamics performance and reducing the monorail running wheel wear is achieved. Then，a coupling kinetics model of monorail vehicle with differential mechanism is established. Compared with conventional monorail vehicles，the longitudinal force and aligning torque of the monorail vehicle with differential mechanism in passing curve sections are obviously reduced，resulting in better dynamics performance and effective control of the running wheel wear.
