Analysis of Vibration Reduction Characteristics and Applicability of Steel-spring Floating-slab Track
The coupled dynamics computation model of metro vehicle along with steel -spring floating-slab track is created based on the theory of vehicle -track coupled dynamics, which also provides the basis to the influence analysis on the time and frequency domain characteristics of steel -spring fulcrum force affected by some factors ,such as the thickness , length and mass of floating-slab, spring rate and its arrangement space as well as running speed and so forth. It can be concluded that, it is quite significant, in the optimization modular design of the parameters of steel-spring floating-slab track,to take the matching relationship of both the amplitude frequency characteristics of steel-spring fulcrum force and natural vibration characteristics of integrated structures into comprehensive consideration, combined with two integrated project cases of metro along with buildings whose natu -ral vibration characteristics are distinct. In this way, on the one hand , the steel-spring floating-slab track which is still expensive can be economically and efficiently put to use according to the site condition. On the other hand ,the economic losses and bad social impacts resulted from the covibra -tion during use of steel-spring floating-slab track can be avoided.
