高速铁路桥上不同轨枕型式动力特性对比
Comparative Study on Dynamic Characteristics of Different Sleeper Types on Bridge in High Speed Railway
摘要
Abstract
Based on the investigation and analysis of different sleeper types at home and abroad, primary schemes of sleeper type on bridge in high speed railway were determined according to the structure characteristics of ballast track on bridge in high speed railway of China. The sleeper types proposed in the primary schemes including type m sleeper, wide sleeper, ladder sleeper and frame sleeper. Then a vehicle-track-bridge coupling system dynamic analysis model was established, with which the dynamic performances of the primary selected sleeper types were compared and analyzed to select the suitable sleeper type for bridge. The selected sleeper type was optimized, and the wide sleeper isrecommended for high speed railway in China. Based on a comprehensive consideration of the track maintenance, type IE sleeper was proposed for sleeper scheme. The dynamic analysis results show that the widening sleeper with 2~4 cm type DI sleeper can well reduce ballast stress and be easy to maintain. Study results are helpful for the design of new sleeper structures on bridge.关键词
