Vibration and Control

Institution
University of Liverpool · Department of Engineering
Qualifications
MPhilPhD

Entry requirements

Research in this field requires a strong interest in vibration and control theory and high motivation. In-depth mathematics (partial or ordinary differential equations, linear algebra, depending on projects) is essential. Most projects also require good programming skills in Matlab and/or Nastran or ABAQUS or Ansys. Many projects involve modal tests or engine tests. Successful completion of projects makes high-quality dynamicists and engineers. Applications from international students are welcome. International qualifications will be evaluated in line with the National Recognition Information Centre (NARIC) guidelines.

Course content

The Centre for Engineering Dynamics in the University of Liverpool is world-renowned for its research in the broad field of Vibration and Control. Research on modal testing and inverse analysis, moving-load dynamics, and vibration and engine control is particularly strong.

Subject Overview

Modal testing allows frequencies and modes of a structure to be obtained, which are used to identify material and geometric properties, in particular for joints. Model updating is systematic ways of correcting a theoretical model that has errors due to inevitable uncertainty and assumptions, using test data.

Structures can be modified to restore the original health or acquire desirable performance. A receptance-based inverse methodology that uses pure test data and does not need a theoretical model of the structure is developed for passive and active control of eigen-structures and has been implemented on laboratory rigs and real engineering structures (e.g., a Lynx helicopter)

Moving loads can excite large-amplitude vibration of a wide frequency range. Modelling and control of moving-load-excited vibration are under constant development with background in automotive and railway engineering. Friction-induced vibration is studied for quite brake design.

Modern I.C. engine technologies involve an increasing number of control actuators to realise efficiency benefits under legislated emission constraints, particularly in transient dynamic conditions. New optimal control techniques are being developed with industry partners Ford and Jaguar Land Rover. Another recent development is laser ignition for realising improved combustion control in next generation gasoline direct injection engines.
