The paper develops a new methodolog y of FE modelling and simulation of the bridge – track – moving train system with the use of CAE systems. The KNI 140070 viaduct of span length 14.40 m, located on the Polish Central Main Line, has been selected. The modernized track contains: 60E1 main rails equipped with Vossloh 300-1 fasteners, 60E1 side rails with SB3 fas teners, B 320 U60 sleepers, crush...

Steel-concrete composite girder bridges, in essence, are thin-walled structures, the dynamic responses of which will be greater than those a typical Euler–Bernoulli beam under train-bridge interaction because shear lag and interface slip. Thus, this study, analysis model train-composite box bridge-multiple tuned mass damper (MTMD) coupling system is proposed, with derived equations time-varying...

This paper discusses the damping measurements on cables with real-time controlled MR dampers that were performed on a laboratory scale single strand cable and on cables of the Sutong Bridge, China. The control approach aims at producing amplitude and frequency independent cable damping which is confirmed by the tests. The experimentally obtained cable damping in comparison to the theoretical va...

Wireless sensors have been proposed for use in structural health monitoring systems because they offer low-installation costs and automated data processing functionality. To validate the performance of the proposed WiMMS (wireless modular monitoring system) on the vibration measurement of large-scale civil structures, a three-story half-scale steel structure is instrumented with a wireless moni...

Abstract The parameters optimization of a viscous damper is carried out with cable-stayed bridge single cable plane and tower. Based on five four functions energy dissipation structure, the relationship between each function obtained. Finally, spatial distribution surface multi-parameter objective constructed, final result process shows that reasonable can effectively inhibit vibration structur...

The work deals with a newly developed prototype of an electrical control unit (ECU) for magnetorheological (MR) damper powered by energy harvested from vibrations. ECU, consisting rectifying bridge, driver unit, microcontroller, and internal power supply system, is advanced version the specially designed processing system vibrations use this to MR damper. Unlike typical in which circuits are ex...

The utilization of passive energy dissipation systems has been created a revolution in the structural engineering industry due to their advantages. Fluid Viscous Damper (FVD) is one of these control systems. It has been used in many different industries, such as the army, aerospace, bridge, and building structures. One of the essential questions about this system is how it can combine with the ...
