The increasing traffic demand is continuously growing worldwide. Therefore, the life of a large stock of bridges that still exist throughout the world must be extended, ensuring at the same time that safety is not compromised for economic reason. This paper introduces the possibility to control the fatigue life of existing bridges by using a vibration control system. Based on a dynamic optimization analysis, the stresses from traffic on the bridge are obtained. Subsequently, a plate finite element (FE) model of the whole bridge is developed. The equation of motion is presented for a case study bridge, equipped with different tuned mass damper system, and the combination of external loads and train/track interaction with or without the TMD system is developed through own-developed routines and FEM software. The procedure is showcased for a case study bridge. After gaining the stress states at the critical hotspot, the fatigue crack life is evaluated by using the linear cumulative damage theory. The different TMD solution presented is demonstrated to be able to diminish the stress level in critical hotspots, improving the overall fatigue life of the bridge over an established lifetime.

“…Passive control element involves some form of structural category, its often including the use of springs and dampers while an active control element such as sensors, actuators and some form of electronic control system can be used to provide more reliability of the control system and that leads to make a reduction in the measurement of vibration level [4][5][6][7][8]. Over the last decade, it can be noted that the various configuration of damper mass spring systems has been arranged and developed to meet different design requirements of the engineering application system to maintain control action [8][9][10]. Lots of employed mechanical structure contain spring element in addition to shock absorber which can be considered as the most important elements in reduction the structural vibration [5][6][7].…”

This work is concerned with investigation the effect of the stiffness coefficient for the spring elements in the mechatronics applied system consists of damper mass spring system linked to the electrical position sensor. The suggested approach contains experimental work as well as theoretical analysis to meet the demand of the proposed system. In the application of the system; the practical work requires to set up a test rig involves the apparatus as well as three models of spring which has been selected to achieve the desired performance. It has been treated as un-damped vibrations case to measure the tolerance in the displacement distance with respect to specified reference point due to apply various values of mechanical load. The electrical position sensor has been used to convert the obtained values of the displacement distance to corresponding value of electrical signal which has been sent to electrical control unit. Comparison between practical and theoretical results has been carried out to realize the best results of the employed system. The simulation process results with using Matlab software package showed that there is a much greater similarity between the obtained practical and theoretical results and the proposed model can be applied with high efficiency. The little bit difference between theoretical and practical results may be occurred due to the accuracy of the employed measurement devices.

“…Kahya et al designed a series multiple tuned mass damper (STMD) device consisting of two in series connected spring-mass-damper units. The assembly was shown that can effectively suppress the resonance introduced from high-speed trains (HSTs), being at the same time economical and sufficiently robust to detuning effects [20] . Yau proposed a string-type tuned mass damper composed of a distributed TMD subsystem and a stretched string acting on a simple beam.…”

This paper investigates the potential of a vibration control-inspired method towards extending the fatigue life of railway steel bridges. Based on coupled thermal-mechanical and vehicle-track analysis, both the residual stresses from welding and these from traffic on the bridge are obtained. Subsequently, a multi-scale approach with a shell Finite Element (FE) model of the whole bridge and a solid FE model of its critical joints is put forward. The equation of motion is established for the controlled bridge, equipped with a Magnetorheological-Tuned Mass Damper (MR-TMD) system, while the combination of excitation, welding and control effects is practiced through own-developed packages and commercial software sub-model routines. The framework is showcased for the study of the Poyang Lake Railway Bridge in China. After obtaining the controlled stress states at the critical welded joint, the fatigue crack initial life is evaluated by using the critical plane method and the linear cumulative damage theory. Simulation results indicate that the multi-scale modelling approach followed, meets the accuracy needs for capturing the cracking process of the welded joint with high computational efficiency. The MR-TMD system, even when moderately reducing the critical joint stress amplitudes, can improve substantially the overall bridge fatigue resistance over the uncontrolled structure.
