Abstract In recent years, there has been a surge of interest in modal-based monitoring systems, especially for bridge structures, to detect damage at an early stage and extend the life existing bridges as well minimize maintenance costs. The modal parameters, natural frequencies mode shapes, depend on stiffness mass structure. For economic application system, estimation parameters based Operati...

Bridge vibration control is an important issue whose purpose is to extend the structural service life of bridges. Normally, the bridge is modeled as an elastic beam or plate subject to a moving vehicle. However, the moving truck on a bridge is a complicated problem that must still be researched. In this paper, we propose a new method, to overcome the huge load in the bridge a load cell is used ...

In this paper, analysis of cascaded H-bridge multilevel inverter in DTC-SVM (Direct Torque Control-Space Vector Modulation) based induction motor drive for FCEV (Fuel Cell Electric Vehicle) is presented. Cascaded H-bridge multilevel inverter uses multiple series units of H-bridge power cells to achieve medium-voltage operation and low harmonic distortion. In FCEV, a fuel cell stack is used as t...

Track–bridge interaction (TBI) is an increasingly essential consideration for the design and operation of railway bridges, especially innovative bridge structure systems that constantly spring up over years. This paper focuses on characteristics additional forces in continuous welded rails (CWRs) 3 × 70 m integral rigid-frame Fuzhou–Xiamen High-Speed Railway, which a novel high-speed (HSR) syst...
