地铁用嵌入式轨道调轨组件优化设计研究
Research on Optimal Design of Embedded Rail Track Assembly for Metro
摘要
Abstract
As a new type of vibration reduction track,the embedded track has changed the characteristics of the traditional track structure.The track assembly is a key component of the embedded track for fine construction,status maintenance and tank maintenance of the track,and the optimal design of the parameters of the stress on the improvement of rail tank system is significant to improve the quality of metro rail and track irregularity.According to the characteristics of subway load,the spatial finite element model of the embedded rail bearing groove system is established to analyze such key parameters as elastic module,key size and spacing related to rail track assembly.The results show that:in order to ensure the structural strength,sufficient support capacity and high track smoothness,the adjustable rail component elastic modulus range should be 0.4 ～ 0.8 GPa,the width should be 60 ～ 80 mm,spacing should be 600 ～ 1 000 mm,and the number of component group of each track slab of some 5m should not be less than 5.关键词
