In this chapter, the general procedure and key issues on adopting an active control device, the active mass damper (AMD), for vibration control of cable stayed bridges under construction are presented.
Vibratec is active in the marine and offshore industry, construction, infrastructure, industry, power generation and defence. The wide range of products ensures
In this paper, we are interested in designing a suitable boundary control to suppress axial vibration in a varying-length mining cable. The existence of a solution to the closed loop system is

EKN supports NKT and Hitachi Energy with guarantees for high-voltage DC cables, crucial for renewable energy projects. Learn how Swedish cables connect wind farms to national
Since the Uddevalla cable-stayed bridge has a relative long span and large slenderness, it is a dynamically sensitive structure subjected to random load environments in the windy coastal region...
The Swedish national grid is based on alternating current (AC) technology, being the dominating technology in all stages of electricity supply. 400 kV overhead power lines are most commonly used
This paper deals with the assessment of cable forces in existing cable supported bridges using the ambient vibration method. A case study of the Älvsborg suspension bridge in Sweden is presented.
Abstract The main cables of suspension bridges show a changing cross-sectional shape with the evolution of construction phases, and they may suffer from severe wind-induced vibrations at
Galloping of cables with ice accumulations. Aerodynamic excitation of overall bridge modes of vibration involving cable motion. Motions due to buffeting by wind turbulence. Motion due to
Cable forces and cable damping values are very important both during and after construction as well as for monitoring. DYWIDAG offers vibration measurement for tension members to quickly and

NKT has begun construction work on a new cable extrusion tower for a power cable factory in Karlskrona, Sweden.
The wind-induced vibration of cables has been widely studied over the past decades because of cables'' many applications in cable-stayed, suspension, and tied-arched bridges, and power transmission
Analysis, Evaluation, and Testing Mechanics of Wind-Induced Vibrations There are a number of mechanisms that can possibly lead to vibrations of stay cables:
