This paper focuses on the vibration control issue of a Flexibly Supported Parallel Manipulator (FSPM), which consists of a flexible support and a rigid parallel manipulator. The distinct characteristic of an FSPM is the dynamic coupling between the rigid and flexible parts, which challenges the vibration control implemented by the rigid parallel manipulator. The re...

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...

In a cable-stayed bridge the bridge deck is supported by a large number of inclined cables of varying lengths and inclinations, which are suspended from a bridge tower. Vertical excitation of the bridge deck, for example, due to traffic loading, is influencing the cables. This may result in quite complex dynamics of those cables, whose basic vibration modes are near resonances with the excitati...

This paper presents results of experiments carried out on free vibrations of a cable with an attached magnetorheological (MR) damper. The attention is focused on the analysis of amplitude dependent damping of a cable with an MR damper operating in passive and controlled modes. In the case of the passive system, damping characteristics are nonlinear and display relevant drawbacks of the system. ...

For cable bridges, the cable tension force plays a crucial role in their construction, assessment and long-term structural health monitoring. Cable tension forces vary in real time with the change of the moving vehicle loads and environmental effects, and this continual variation in tension force may cause fatigue damage of a cable. Traditional vibration-based cable tension force estimation met...

As the demands for reliable, real-time automation and process control in industrial environments increase, an Industrial Ethernet cabling system quickly becomes the most attractive solution. Cables used in industrial environments must be designed to work in harsh environments of temperature extremes, humidity, and vibration. Many times this can exceed the ranges for information technology equip...

The current paper describes the development and implementation of a vision system in the context of the monitoring of a cable-stayed bridge, discussing the major requirements, the cost of the instruments, the particular aspects of the developed image processing algorithms, the integration in a conventional monitoring system and the results of application to the International Guadiana Bridge in ...

The girder of self-anchored suspension bridge is subjected to large compression force applied by main cables. So, serious damage of the girder due to breakage of hangers may cause the collapse of the whole bridge. With the time increasing, the hangers may break suddenly for their resistance capacities decrease due to corrosion. Using nonlinear static and dynamic analysis methods and adopting 3D...
