| Abstract: | Based on the finite element theory, the paper sets up calculation model for slab track structure with elastic long sleeper and it simulates whole process loaded test. The dynamic characteristics of track and damping performance are analyzed. Meanwhile the proper range of the under-rail stiffness is also analyzed, so the paper provides guidance for maintenance, installation and design of slab track structure with elastic long sleeper. |
