摘要:
［目的］目前应用于轻轨线路铰接式列车的设计速度为100km/h，这样的速度等级在一定程度上制约了轻轨线路向市郊、卫星城等区域扩展，有必要对轻轨120km/h铰接式列车的总体设计、转向架设计、铰接装置设计等关键技术开展深入研究。［方法］基于轻轨线路的条件、特点及列车技术参数，确定了轻轨120km/h铰接式列车总体设计的边界条件。提出了轻轨120km/h铰接式列车总体设计方案，确定了列车的主要技术参数值。采用理论分析、仿真模拟及台架试验等方法，获取精确的动力学参数，对铰接装置的结构强度、转向架构架强度及车辆系统动力学响应等进行了全面的分析与评估。［结果及结论］该型铰接式列车的总体设计方案、转向架设计方案及车端连接设计方案可以有效优化转向架悬挂系统与轮轨的关系，提升列车在曲线区段的通过能力，提升列车运行的稳定性和安全性。
Abstracts:
［Objective］ Currently, the design speed of articulated LRV (light rail vehicle) is 100 km/h, which somewhat restricts the expansion of light rail lines to the suburbs, satellite cities, and other areas. Therefore, it is necessary to conduct in-depth research on key technologies for 120 km/h articulated LRV transit, including designs for the overall train, bogie and articulation devices. ［Method］ Based on the conditions and characteristics of LRV lines and the vehicle technical parameters, the boundary conditions for the overall design of 120 km/h LRV are determined. An overall design scheme for the 120 km/h articulated LRV is proposed, and the main train technical parameters are established. Through theoretical analysis, simulation modeling, and bench tests, precise dynamic parameters are obtained. Comprehensive analysis and evaluation are performed on the structural strength of the articulation devices, the bogie frame strength, and the dynamic responses of the vehicle system. ［Result & Conclusion］ The overall design scheme, bogie design scheme, and vehicle-end connection design scheme for this type of articulated train can effectively optimize the relationship between the bogie suspension system and the wheel-rail interaction, improve the train capability to negotiate curved sections, and enhance operational stability and safety.
