Active control of quarter-car and bridge vibrations using the sliding mode control
In this study, the active control of the three-degree-of-freedom quarter-car suspension system passing over the bridge, which can be modeled as an Euler-Bernoulli beam, is studied. The mathematical model of the bridge and ... -
Application of magnetic field to reduce the forced response of steel bridges to high speed train
This paper uses a train-track-bridge interaction system to assess the dynamic performance of railway bridges exposed to a high-speed train and magnetic field. A 24° of freedom 3D train model and thin steel bridge beam are ... -
Comparative analysis of full car model with driver using PID and LQR controllers
In this study, an active suspension model is proposed to increase the driving safety and passenger comfort of the car, which is adversely affected by car-road interaction. In this context, the full car model with a driver ... -
Dynamic analysis of high-speed train moving on perforated Timoshenko and Euler–Bernoulli beams
This study investigates the numerical simulation of the interaction between a high-speed train and perforated beams. The perforated bridge beam is modeled according to Timoshenko and Euler–Bernoulli beam theories with a ... -
Effect of Functionally Graded Carbon Nanotube Reinforcement on the Dynamic Response of Composite Beams Subjected to a Moving Charge
Purpose: This article examines the forced vibrations of composite beams that have been reinforced with single-walled carbon nanotubes (SWCNTs) and subjected to a moving charge without considering the effect of mass inertia. ... -
The effect of the viscoelastic support and GRPL-reinforced foam material on the thermomechanical vibration response of piezomagnetic sandwich nanosensor plates
This paper investigates the vibration characteristics of a sandwich nanosensor plate composed of piezoelectric materials, specifically barium and cobalt, in the upper and lower layers, and a core material consisting of ... -
A new expert system for active vibration control (AVC) for high-speed train moving on a flexible structure and PID optimization using MOGA and NSGA-II algorithms
Koç M.A. (Springer Science and Business Media Deutschland GmbH, 2022)As the maximum operating speeds of high-speed trains (HST) increase, the vibrations transmitted to the vehicle body increase as well. If the HST is moving on a structure such as a bridge, resonant frequencies due to ... -
Train-structure interaction for high-speed trains using a full 3D train model
In high-speed trains, the driving safety and passenger comfort of the railway vehicle are negatively affected due to the problem of interaction between the train and the bridge. Among these problems are rail irregularities, ...
