### MECHGR04 Vibrations, Airborne and Underwater Acoustics & Control

 Code MECHGR04 Alt. Codes(s) very similar to MECHGM04, MECHM008 Title Vibrations, Airborne and Underwater Acoustics & Control Level MSc, MEng UCL Credits/ECTS 15 / 7.5 Start September End March Taught by Dr Paul Fromme (33%) Module Coordinator Prof Nader Saffari (33%) Dr D. Western (33%)

Prerequisites

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

Assessment

The course has the following assessment components:

• Written Examination (2 hours, 100%) answer 3 mandatory questions (one each from Vibrations, Control and Acoustics).

To pass this course, students must:

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