Dynamic Simulation Calculation and Adaptability Analysis of Rubber Floating Slab Track of Beijing Underground Transit Line
摘要
Abstract
The adaptability analysis is performed at two environmental vibration sensitive points of Beijing underground transit line located in the small radius and large gradient sections. To provide a theoretical basis for the selection of vibration damping track structures near the environmental vibration sensitive points and the vibration control of the main line railway. Based on the finite element software, the three-dimensional dynamic analysis model for rain-rubber floating slab track-tunnel foundation is established to analyze the transfer characteristics, the dynamic calculation and adaptability of the most unfavorable working conditions. Research results show that (1) the natural frequency of rubber floating slab track is 16. 75 Hz, and its vibration isolation effect becomes obvious beyond 27. 3 Hz;(2) dynamic simulation calculation of rubber floating slab track is performed under EMU and SS9 locomotive load on both tangent and curve lines, and it is concluded that the riding comfort and the security of the rubber floating slab track meet the requirements of relevant standards and codes.关键词
