The smart cable with embedded distributed fiber optical Bragg grating (FBG) sensors was chosen as the object to study a new diagnosis method about broken wires of bridge cable. The diagnosis strategy based on cable force and stress distribution state of steel wires was put forward. By establishing bridge cable and cable steel wires model, the broken wires sample database was simulated numerical...

A steady-state dynamic model of a cable in air is put forward by using some tensor relations. For the dynamic motion of a long-span Cable-Driven Parallel Robot CDPR system, a driven cable deployment and retrieval mathematical model of CDPR is developed by employing lumped mass method. The effects of cable mass are taken into account. The boundary condition of cable and initial values of equatio...

This paper presents the bridge cable inspection robot developed in Korea. Two types of the cable inspection robots were developed for cable-suspension bridges and cable-stayed bridge. The design of the robot system and performance of the NDT techniques associated with the cable inspection robot are discussed. A review on recent advances in emerging robot-based inspection technologies for bridge...

Cable theory has been developed over the last decade, usually assuming that the extracellular space around membranes is a perfect resistor. However, extracellular media may display more complex electrical properties due to various phenomena, such as polarization, ionic diffusion, or capacitive effects, but their impact on cable properties is not known. In this paper, we generalize cable theory ...

Abstract. Nowadays, high accuracy measurements provided by terrestrial laser scanner and vision sensors allow to collect useful exhaustive information about the conditions of existing structures, detect defects geometry anomalies better understand their mechanical behavior. These avant-garde technologies were found be particularly effective for structural health assessment cable-stayed pedestri...

The changes of the seabed environment caused by a natural disaster or human activities dramatically affect the life span of the subsea buried cable. It is essential to track the cable route in order to inspect the condition of the buried cable and protect its surviving seabed environment. The magnetic sensor is instrumental in guiding the remotely-operated vehicle (ROV) to track and inspect the...

Single row cable reels are often used in the study of by heavy port machinery equipment, but there problems less capacity and larger circumferential space. In design traditional drum concept principle as basis, on basis structure optimization strength check. According to parameters, it is concluded that winding occupies space, arranged a regular order can accommodate large amount cable. this pa...

At the leading edge of healing embryonic epithelium, cables of actin filaments appear to extend from cell to cell, forming a ring around the wound circumference. It has been hypothesized that this actin filament cable functions as a contractile 'purse string' to facilitate wound closure. We have observed this cable in large, circular healing epithelial wounds in corneas of adult mice. To elucid...

Cable winding is an alternative technology to create stator windings in large electrical machines. Today such cable winding is performed manually, which is very repetitive, time-consuming and therefore also expensive. This paper presents the design, function and control system of a developed cable feeder tool for robotized stator cable winding. The presented tool was able to catch a cable insid...
