a large number of authors have studied to find out how to control scouring around a pier along direct stream. the objective of this research is then to study a scour pattern around such piers on curves rivers due to the fact that there may be a difference between a flow pattern on a direct line and the meander. thus, this study tries to check whether the use of cable and collar alone and in a c...

Cables or suspenders are the critical force-transmitting components of cable-supported bridges, and their timely tension monitoring is consequently most important issue in corresponding structural health monitoring. However, very few works regarding full automation vibration-based estimation have been reported literature. To develop a system cable based on real-time vibration signals, this rese...

Large payloads hoisted by overhead cranes exhibit the same behavior as that of a double-pendulum. Changes in hoisting cable length during payload transfer maneuvers give rise to time-dependent system frequencies rendering input-shaped commands ineffective. In this paper, frequency-modulation input-shaping strategy enables simultaneous hoist and travel using single-mode is presented. This utiliz...

Solitons are a unique class of pulse-shaped waves that propagate in nonlinear dispersive media. In the course of propagation, they maintain spatial confinement of wave energy within the pulse shape without dispersion and exhibit remarkable nonlinear dynamics. Solitons are found throughout nature where fine balance between nonlinearity and dispersion is achieved. Dispersion alone would flatten o...

There are many auxiliaries with high rotating speed in a power plant, such as pumps, fans, motors and so on. To warrant their safe and reliable operation, their state of vibration has to be monitored. But because of their scattered location, the traditional way of online monitoring with shielded cable connections is costly and work expensive and the precision, reliability and safety of itineran...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

This paper studies the dynamics and control of the Gough–Stewart platform for vibration control of a flexible supporting structure. The problem arises from a large radio telescope in which the astronomical equipment is mounted on a platform to be stabilized by a Gough–Stewart platform, while the base platform of the mechanism itself is carried by a vibrating cable-car that moves along flexible ...

As a testbed for various structural health monitoring (SHM) technologies, a super-tall structure – the 610 m-tall Guangzhou Television and Sightseeing Tower (GTST) in southern China – is currently under construction. This study aims to explore state-of-the-art wireless sensing technologies for monitoring the ambient vibration of such a super-tall structure during construction. The very nature o...
