“…In the case of discrete models, as is the case of integrated models, numerical analysis using the vehicle/track system model was carried out using the DIASTARSIII program, developed by the Railway Technical Research Institute [4,5], which analyzes dynamic interaction between the vehicle and railway structure. Also, numerical analysis using the track/structure system model was carried out using the DIARIST general purpose structure program for the track structure [6].…”

“…Until now, the entire system consisting of vehicle/track/structure has been modeled [3] (hereafter called an "integrated model"). We used the DIASTARSIII program for numerical analysis, which (c) A standard RC girders Cantilever slab [4], which analyzes the dynamic interaction between the vehicle and railway structure. However, there is a problem that most of the structure vibration modes (mainly lower than 100Hz) existed in order that were even lower than those of the rail vibration modes (mainly higher than several hundreds Hz), so if an attempt is made to reproduce the high order modes of the rails, the number of orders of the vibration modes to be taken into account become extremely large, necessitating a large time to carry out each analysis.…”

Abstract. In order to analyze effectively the vibration response of the structure members of railway reinforced concrete viaducts, we have developed a new analysis method. It divides the whole railway system into vehicles/track model, and the track/structure model. Using these models, we examined the influence of various parameters of the vehicle, track and structure on the structure member vibration. As a result, the following has become clear. For example, for 20Hz or more, unsprung wheelset mass has a great influence on response of structure member. For 20-100Hz and 150Hz or more, rail surface roughness, for 60Hz or more, the stiffness of the rail pad, for less than 60Hz, the stiffness of the slab of structure and so on, have great influence on structure member vibration respectively.

Abstract. In this paper, numerical experiments about the structure borne sound countermeasures were conducted, by paying attention to the structure vibration of RC girder. Numerical experiments for the vehicle/track system model was carried out using the DIASTARSIII program, developed by the Railway Technical Research Institute, which analyzes dynamic interaction between the vehicle and railway structure. Also, numerical analysis for the track/structure system model was carried out using the DIARIST program for the track structure. As a result, we elucidated the vibration reduction effect of various countermeasures. First, vibration reduction effect of soft track pad of 30MN/m is recognized in the frequency band above about 70 Hz by measurement results and analysis results. Second, the frequency band which obtained reduction effect depends a great deal on natural frequency of vibrationreducing track.

“…RTRI, too, has been active in this area, having developed a vibration analysis method [5] based on a three-dimensional coupled vibration analysis model of cars, a track and supporting infrastructures and utilizing it in studying dynamic interaction between cars and structures. Another example is a ground vibration generation model [6] based on an analysis model of a spring-mass system and double beams on an elastic foundation, which has been used to study the effects of adopting lighter cars and tracks with lower spring coefficients on vibration mitigation.…”
