Abstract

Subjecting structures to external forces inevitably leads to the generation of vibrations. For high-rise and flexible structures, excessive vibrations can significantly impact their normal operation and structural integrity. To mitigate these undesirable vibrations, structural vibration control is essential. Among various passive control methods, the tuned mass damper (TMD) is widely used for its ability to reduce vibrations through resonance with the structure. Meanwhile, the active mass damper (AMD) can also achieve an excellent control efficiency by exerting active control force on structures. Hybrid control integrates the benefits of multiple control strategies and applies the control forces on the same structure simultaneously. Hybrid mass damper (HMD) combines the passive characteristics of TMD and the active features of AMD, overcoming the limitations associated with using either system in isolation. This paper proposes a novel hybrid control method based on virtual TMD algorithm and optimizes the parameters of HMD by weighting the structural response and stroke of HMD to improve the comprehensive control performance. The effectiveness of this optimization is substantiated in the frequency domain. Additionally, numerical simulations are conducted to compare the optimized HMD with the traditional TMD and the unoptimized HMD, demonstrating both the effectiveness of the optimization and the superior control performance of the optimized HMD. The numerical results indicate that the optimized HMD reduces stroke by 15.6% compared to the unoptimized HMD on the premise that the control effect only loses 2.4%. Overall, the optimized HMD demonstrates superior comprehensive control performance relative to the unoptimized HMD.

In the paper, the MATLAB-Simulink model of simulation of operation of the fast light innovative regional train from “Serbian Railways” in traction and braking mode is exposed where changes are observed: stator currents of three-phase traction motors, traction electric motor speeds and electric multiple units, electromagnetic torque on the rotor shaft of the traction electric motor, and direct current bus voltage. The model allowed review of the listed parameters for: different allowed values of contact network voltage and total voltage distortion at the place of connection of the electric multiple unit to the contact network; different mechanical loads of the electric multiple unit and traction electric motor; and different train speeds and rotations of traction electric motors. Appropriate conclusions were made through the analysis of the simulation results obtained.

This paper defines vehicles and buildings as main sources of United Kingdom (UK) carbon dioxide (CO₂) and seeks to cut such emissions using green hydrogen made from combined wind and solar energy. Combustion vehicles powered by fossil petroleum emit near half of UK climate-warming CO₂ while buildings heated by natural gas provide a third. First, current UK grid problems are defined: Electricity, gas and petroleum grids. Refueling green vehicles has been a particular problem. Then experiments on the private wire community of Keele University show how green hydrogen could integrate both green vehicles and buildings. Next, the model supply chain is planned and tested. Finally, experiments and calculations are outlined, analyzing the optimum system design criteria proposed. We conclude that economic green hydrogen can displace petroleum in vehicles, while powering buildings instead of natural gas. Also, the prospect in 2024 is that profits can be made all along the green hydrogen supply chain, such that new businesses involved in local private clean communities can cost less than the National Grid monopoly and other dominant fossil energy companies.

Presently, dynamic impacts occurrences caused by car crashes have been frequently reported. Statistical results from different articles indicate that vehicle crashworthiness of bridge pier supersedes the other events. However, majority of the published articles focusses on sustainability and finding severity of distressed pier due to impact correlating faster construction methods, like accelerated bridge construction (ABC). This article is an attempt to examine post impacted behavior of a commonly used connector in ABC for resisting short duration shock. Static and dynamic performance analyses of a connector embedded within a coupler system has been examined. A representative ABC pier with the standardized and selected material properties collected from manufacturer’s data has been utilized. Coupler composite materials consisting of a hollow uniform cross-section cast iron cylinder filled up with specified concrete grout conforms higher strength. The performance examination has been conducted by numerical modeling using finite element method (FEM). A commercially used software ANSYS has been utilized for carrying out the simulations. To investigate the post impact dynamic behavior, mesh-independent studies seems inevitable and hence are executed to evaluate dynamic impact factor (DIF). Sensitivity studies are carried out for validating results in precision. The DIF of the main reinforcing tensile steel embedded into the grout placed inside the connector has been determined. Results captured from simulations to identify material properties at plastic stage in sustaining such load have been conducted. The results provide significant information that aids opting for selecting suitable connectors for attaining help the design offices.
