“…The numerical model consists of the train-track sub-model and the track-tunnel-surrounding soil sub-model, which was verified by the result of the in-site test in Xi'an subway line 2, Shanxi province, China. Through the numerical model coupled with the multi-island genetic algorithm, the vibration level was improved by 4 …”

“…Using the two-dimensional model, both the discontinuous floating slab and the continuous floating slab can be analyzed. Cui and Chew [4] analyzed the effectiveness of the discontinuous floating-slab track to stationary/moving harmonic loads by the receptance method. Hussein and Hunt [7][8][9] studied the discontinuous/continuous floating-slab track by the Fourier-Repeating-unit method, the Periodic-Fourier method and the Modified-phase method.…”

Abstract. The floating-slab track is one of the best methods to reduce the vibration from the underground railway. In this paper, the rubber floating-slab track was studied. The train-track model coupled with the track-tunnel-surrounding soil model was built, which was verified by the results of the in-site test. Through this model, the quality of the rubber floating-slab track was optimized by the multi-island genetic algorithm.

“…The floating slab tracks have been widely used to control vibration from underground trains in urban rail transit. Cui and Chew [16] investigated the effectiveness of a floating slab track system to stationary harmonic loads and moving harmonic loads by using the reacceptance method. Hunt [17], and Hussein and Hunt [18] discussed modelling of floating slab tracks on rigid foundations; the Fourier transformation method was used to calculate track displacements under an oscillating moving load.…”

a b s t r a c tIn this paper, the problem of vibration transmission from slab track structures into bridge is studied by theoretical analysis. A vehicle-track-bridge coupling system dynamics model is established based on a multibody dynamics theory and a finite element method. The system model consists of vehicle model, track-bridge model and wheel/rail interaction model. The vehicle model is established based on the multibody dynamics theory, and the tack-bridge model is established by the finite element method. The vehicle model and track-bridge model are coupled through wheel/rail interaction model, and the track irregularities are included. The system dynamic responses are calculated, and the effectiveness of elastic materials in vibration reducing is discussed. The results demonstrate that elastic materials like slab mat layer inserted between slab track and bridge can reduce vibration transmitted from track into the bridge. Some suggestions for the design and application of slab mat are provided in the end of the paper.

Abstract:A coupled dynamics computation model for metro vehicles, along with a steel-spring floating-slab track, is developed based on the theory of vehicle-track coupled dynamics. Using the developed model, the influences of the thickness, length and mass of floating-slab, spring rate and its arrangement space, running speed, etc. on the time and frequency domain characteristics of steel-spring fulcrum force are analyzed. The applicability of steel-spring floatingslab track is discussed through two integrated example cases of metro and buildings possessing distinct natural vibration characteristics. It is 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. In this way the expensive steel-spring floating-slab track can be economically and efficiently utilized according to the site condition, and at the same time, the economic losses and bad social impact resulted from the resonance during usage of steel-spring floating-slab track can be avoided.
