摘要
Abstract
Due to the installation of high elastic damper fasteners,the track flexibility can be increased,so that the transfer of vibration and noise can be effectively reduced.However,the train running state is inevitably affected.The influence of QY-2 fastener on train running stability is investigated through testing and analyzing the train vibration acceleration when passing the track of QY-2 fastener and ZX-2 fastener in Nanjing Airport Line.The results show that QY-2 fastener can effectively ensure the smooth running.The vertical and lateral sperling index can reach the first class level.关键词
