宁波轨道交通车辆底架设备悬挂方案分析与比较

Analysis and Comparison for under Frame Equipment Suspension Scheme of Ningbo Rail Transit Vehicles

宁波轨道交通1号线与2号线一期车辆均为同一公司设计制造的地铁车辆。2种车辆主要差异在车下设备悬挂方案的不同,车辆各项技术参数基本完全一致。通过总结对比2种不同的悬挂方案及应用情况,分析2种车辆对应的设备悬挂平台的特征及差异,为后续车辆设计选型提供参考。

Ningbo rail transit line 1 and line 2 phase I vehicles were designed and manufactured by the same company.The main differences between the two vehicles were the different suspension schemes under the frame,and the technical parameters of the vehicles were basically the same.By summarizing and comparing the two different suspension schemes and their applications,the characteristics and differences of the corresponding equipment suspension platforms of the two vehicles were analyzed,which provided a reference for the subsequent vehicle design and selection.
