摘　　要：根据时速200 km动力集中动车组技术要求,从顶层指标、关键技术等方面进行了非动力转向架技术方案可行性分析。顶层指标主要有速度提升、轴重增加;关键技术包括动力学性能、基础制动配置、旋转部件适应性、承载件结构强度、检修维护性能等。分析结果表明,时速200 km动力集中动车组非动力车转向架可沿用SW-220K型转向架平台进行优化:轴箱轴承采用自密封结构,制动系统控制充分利用动力车电制动力以降低空气制动介入速度。优化后的SW-220K转向架在动力学方面可满足时速200 km动力集中动车组速度提升的需求,关键承载部件强度可满足17 t轴重需求,同时SW-220K型转向架平台可与CR200J型动车组、25T型客车检修维护体系保持一致,技术变更小,成熟可靠,且新造及运维成本能够有效控制。According to the technical requirements of 200 km/h power-centralized EMUs,the paper carries out the feasibility analysis of non-power bogie technical scheme from the aspects of top-level indexes and key technologies,etc.The top-level indexes mainly include speed increase and axle load increase;the key technologies include dynamic performance,basic braking configuration,adaptability of rotating parts,structural strength of bearing parts,inspection and repair as well as maintenance performance,etc.The analysis results show that the bogie of the non-power vehicle of the 200 km/h power centralized EMU can be optimized by using the SW-220K bogie platform.The axle box bearing adopts the self-sealing structure,and the braking system control makes full use of the electric braking force of the power vehicle to reduce the air braking intervention speed.The optimized SW-220K bogie can meet the demand of speed increase of 200 km/h power centralized EMU in dynamics aspect,and the strength of key bearing parts can meet the demand of 17 t axle load.At the same time,the SW-220K bogie platform can be consistent with the CR200J EMU and 25T passenger car maintenance system,the technology is smaller,mature and reliable,and the cost of new construction and operation and maintenance can be effectively controlled.
