Abstract. Recently, there has been an increasing emphasis in the Indirect bridge health monitoring method employing passing vehicles, which is regarded as one of most effective approaches damage screening. However, few researches have conducted on Drive-by inspection using vehicle displacement profile indicator due to challenges measurement and result accuracy. This paper proposes optimization ...

The paper is a summary of the research conducted so far on the ultrafast charging issues of electric vehicles with the main emphasis on the infrastructure. In order to estimate the load curve and peaks resulting from high charging rate, simulations are carried out initially to determine energy and power ratings. Energy storage options for filtering out the perspective peaks are discussed with a...

ABSTRCT: Elastic bearings have been used on simply supported bridges on high-speed railway in Taiwan to isolate train-induced vibration. However, their influence on dynamic behavior of the vehicle and bridge has not been fully investigated, and their vibration attenuation has not been quantificationally discussed. In this study, spring-damper elements with 12 degrees of freedom are established ...

Abstract A new semi-analytical approach to analyze the dynamic response of railway bridges subjected high-speed trains is presented. The bridge modeled as an Euler–Bernoulli beam on viscoelastic supports that account for flexibility and damping underlying soil. track represented by bedding. Complex modal expansion models performed considering non-classical damping, coupling two subsystems achie...

Bridge Weigh-in-Motion systems can be used to estimate vehicle parameters such as velocity, axle loads, or the distance between axles without affecting the traffic. These parameters and the classification of vehicles are necessary to determine vehicle overload and hence may help to reduce risks for road users and road infrastructure and allow optimized planning of maintenance work. The Bridge W...

In this study, active suspension control of the interaction between bridge can be modeled according to Euler-Bernoulli beam theory, and quarter car model with three degrees freedom is studied. The system consists a spring, damper, linear actuator. designed using classical PID self-tuning fuzzy (STFPID) reduce vehicle body's disruptive effects. To determine performance controllers, two different...
