Vibration isolation analysis of elastic bearing based on train-track-bridge coupled vibration model

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 ...

Nonlinear Vibration Analysis of the Composite Cable using Perturbation Method and the Green-Lagrangian Nonlinear Strain

In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...

Dynamic characteristics of the new curved cable-stayed bridge in Porto Marghera (Venice, Italy) from ambient vibration measurements

The paper summarizes the results of recent ambient vibration tests and operational modal analyses carried out on the new curved cable-stayed bridge erected in the Commercial Harbour of Porto Marghera (Venice, Italy). The ambient vibration tests were carried out as a part of the reception tests of the bridge before its opening and included the recordings of the system response in selected points...

Universal Dynamics in Flow-Induced Cable Vibration

A combined analytical-experimental approach is used. Analytical aspects focus on the continued development of a low-order model that utilizes a series of diffusively coupled circle map oscillators along the cylinder span. This coupled map lattice has been extended to include control logic to develop a very efficient low order model for control studies in cylinder wake flows. On the experimental...
