Optimization of 4-span Overlap Section on High-Speed Contact Line System
摘要
Abstract
Rverlap section between two adjacent high-speed suspensions is a weak area of the overhead contact line system. When the pantograph passes through the area at high speed, the vibration is more serious than that in other areas. According to some questions about 4-span overlap section on the existing high-speed railway, such as the abnormal wear between positioner and support in central pole, much supporting uplift in transition pole and unequal height between two suspensions at cross point, a structural optimization plan is proposed. Firstly, the plane layout of the contact line system is adjusted to form 3 kinds of adjustment options, and simulation of pantograph/catenary relationship is employed to establish four kinds of overlap section simulation model. The comparison of the dynamic performance parameters concludes that double-pantograph operation suggested by option 2 is recommended; the maximum supporting uplift appears in transition pole ZJ2; the supporting uplift attenuation in central pole is more slowly than that in other poles;the pantograph /catenary dynamic performance of the adjustment option is better than that of the original design.关键词
