摘　　要：为研究高等级铁路不同接触悬挂类型的性能优势,选取不同接触悬挂类型与不同速度等级的弹性链悬挂和简单链型悬挂接触网系统相匹配,建立CATMOS环境下的有限元模型,对不同系统的弓网动态性能进行比较和分析,研究表明：速度等级为200-250 km/h时,弹性链型悬挂较优;速度等级为300-350 km/h时,综合考虑简单链型悬挂与弹性链型悬挂运行参数指标基本一致。In order to research the performance advantages of different suspension types for high-grade railway, the elastic- ity stitched catenary and simple stitched catenary with different suspension types are closed at different speed grades. The finite element model for different suspension types is built in the CATMOS environment. The comparison and analysis of dy- namic performances of the different suspension types are carried out. The research shows that the performance of elasticity stitched catenary is better when the speed is between 200 km/h to 250 km/h and the parameter index of elasticity stitched catenary and simple stitched catenary is similar under the comprehensive consideration when the speed is between 300 km/h to 350 km/h.
