Parametric study and design optimization of railway sensor brackets for mitigating train-induced vibration

Dynamic Characterization and Vibration Serviceability Evaluation of All-Steel Modular Floor Systems

Lightweight steel floor systems are increasingly being adopted in modern buildings, where vibration serviceability under human-induced loading often governs structural design. This study presents an experimental–numerical investigation to clarify the dynamic mechanisms and serviceability performance of a nontradition...

Design and Vibration Response Analysis of a Novel Lightweight Temporary Steel Platform

To address the limitations of conventional temporary steel platforms, a novel lightweight temporary steel platform (LTSP) system was developed based on an inland river high-pile wharf project. The proposed system utilizes permanent rock-socketed steel tubular piles of the wharf structure as the primary load-bearing fou...

Modal and Forced Vibration Analyses in a Railway Bridge considering Train-Track-Bridge Interaction

This work investigates the dynamic response and modal behaviour of a railway bridge subjected to moving loads by considering complex train-track-bridge interaction (TTBI) models. The bridge structure, comprising simply supported concrete beams, is modelled using 3D Euler–Bernoulli finite elements with Rayleigh damping....

Optimized Design of Vibration Reduction for the Frame Structure of Metering, Considering Ground Impact Load

To effectively mitigate the adverse effects of impact loads on the operational quality of a planter, this paper focuses on precision metering with dual planting chambers, and a novel approach is proposed to concurrently consider static and impact loads in the design of the frame structure, aiming to achieve a balanced...

Integrated finite element and experimental vibration analysis for reliable electric vehicle gearbox design

Electric vehicle (EV) gearboxes need to be light but strong and must handle a large amount of force while working at speed. They also need to stay stable when moving. This study shows a method to test and design EV gearboxes. The gearboxes considered have a 9:1 speed change. The finite element analysis is carried out,...
