摘要:
［目的］现代无轨电车采用多车厢铰接编组方式运行，其铰接位置具有较多自由度，会对车辆的平稳运行造成影响。因此，有必要对车端转角液压装置的设计进行深入研究。［方法］为了减小车辆铰接位置的自由度，增强车辆的抗失稳能力，并辅助车辆转弯，设计了车端转角液压装置，并开展了仿真研究。依据车辆铰接编组的结构特点，遵循车辆对铰接结构的具体要求，制定了车端转角液压装置的总体方案和原理，对关键部件的参数进行了精确计算和合理选型，进而完成了该装置整体结构的设计。通过在Simulink软件中构建仿真模型，对车辆转弯运行过程中车端转角液压装置的动态特性和车辆铰接位置的动态变化进行了模拟分析。［结果及结论］仿真结果表明：所设计的车端转角液压装置在动态运动参数方面满足设计输入的要求，各车辆展现出较高的动态一致性，横摆幅值较小。该装置在提高车辆转向性能和控制车辆失稳方面发挥了关键作用。

［Objective］ Modern ART (autonomous rail transit) trams often adopt multi-car articulated configurations in operation, because articulation joints possess significant degrees of freedom, relating the smooth operation of the vehicles. Therefore, it is essential to conduct in-depth research of the design of vehicle-end turning hydraulic devices. ［Method］ To reduce the vehicle articulation joint freedom degree, enhance vehicle anti-instability capability, and assist in vehicle turning, a vehicle-end turning hydraulic device is designed, accompanied by simulation researches. Based on the structural characteristics of articulated vehicle configurations and specific requirements for articulation structures, the overall scheme and principles of the vehicle-end turning hydraulic device are formulated. Precise calculations and rational selection of key component parameters are performed to complete the design of the overall structure. A simulation model is built using Simulink software to analyze the dynamic characteristics of the vehicle-end turning hydraulic device and the dynamic changes at articulation points during vehicle turning operation. ［Result & Conclusion］ Simulation results show that the designed vehicle-end turning hydraulic device meet the input requirements for dynamic motion parameters, with all vehicles showing high dynamic consistency and minimal yaw amplitude. This device plays a critical role in enhancing vehicle steering performance and controlling instability.
