Module Descriptor

MECHGR04 Vibrations, Airborne and Underwater Acoustics & Control

Alt. Codes(s) MECHM008, very similar to MECHGM04
Title Vibrations, Airborne and Underwater Acoustics & Control
Level MSc, MEng
UCL Credits/ECTS 15 / 6
Start September
End March
Taught by Dr Paul Fromme (70%) Module Coordinator
  Prof Nader Saffari (30%)


Vibrations and Control knowledge equivalent to undergraduate degree in Mechanical Engineering. UG level Solid/Fluid Mechanics. UG level Engineering Mathematics

Course Aims
The Vibrations part of the course reinforces the modelling and vibrations knowledge from UG level. Building on these skills and mathematical tools, vibrations in more realistic and complex structures are investigated and analysed, increasing the understanding of vibration problems in engineering structures. The main aims of this course in digital control systems are:

  • To give students an appreciation of the need for modern control systems
  • To explain and discuss the systems that make up modern control systems
  • To provide students with mathematical tools needed in the design and performance analysis of digital control systems

In the Acoustics part of the course, the aim is to impart knowledge of the sources and nature of acoustic noise in an engineering environment. The coverage starts with basic physical concepts and leads on to the treatment of vibrating structure/fluid interactions for a number of simple examples of practical interest.

Method of Instruction


The course has the following assessment components:

  • Written Examination (2 hours, 65%) answer any 3 questions from 5
  • Worksheet (35%)

To pass this course, students must:

  • Obtain an overall pass mark of 50% for all sections combined

Additional Information
All the material in this module is common to MECHGM04. Students on the MSc Marine Engineering take MECHGR04 instead of MECHGM04. The former includes additional lectures on underwater acoustics. Four of the exam questions are common to both modules, the fifth exam question is on general acoustics for MECHGM04 and on underwater acoustics for MECHGR04.
