PhD Studentship: Active Vibration Control of Underwater Cables

 

Signal Processing & Control Group

 

Location: Highfield Campus


Closing Date: Friday 26 January 2018


Reference: 940517KR


A fully funded industrial CASE studentship is available for a high-quality student to work on the development active control vibration systems for underwater cables. The ideal candidate will have a background in vibration, dynamics, acoustics and/or control engineering.

 

Cable-like structures are used in a variety of engineering applications where their dynamic response is of particular importance. For example, hydrodynamic vortex induced vibration can cause problems in marine risers, tethers and other slender marine structures, which include towed hydrophone arrays. Wave induced vibration can also cause significant levels of vibration in cable-buoy systems and in the civil engineering sector, parametric vibration can cause severe levels of vibration in cable-stayed bridges. Although passive vibration control solutions exist for some of these practical problems, in certain applications they may not provide a sufficient level of vibration control without significant levels of design compromise. For example, fairings designed for towed array cables may reduce vibration at the expense of an increased drag. Therefore, this project will investigate the application of active vibration control technologies to the control of dynamically excited cables under different excitation conditions. The project will consider different methods of actuating the cable to achieve control and, in particular, will investigate a number of different active control strategies. A significant component of the project will focus on experimental testing of the developed control strategies and this will include laboratory tests in both air and underwater. These lab-scale tests will lead to a demonstrator for industrial applications and the potential for larger-scale experimental investigations.

 

This project is supported by a large industrial collaborator, which provides a wide range of potential opportunities for the successful candidate. In particular, the strong industrial connection helps to ensure that the research will have a direct impact on real-world engineering.

 

This position also benefits from a tax-free stipend of between £17,000 and £20,000 depending on the successful candidate’s previous experience. This includes the standard EPSRC studentship and a top-up from the industrial sponsor.


The successful candidate will be based in the Signal Processing and Control Group of the Institute of Sound and Vibration Research. This is home to an internationally renowned research group working in diverse areas of signal processing and control.
