Remarks (specific information about assesment, entry requirements, etc.):
A good understanding of the contents of the four "Prerequisite" courses listed above is essential.
Goals:
Vibration of mechanical systems is wanted in some cases (e.g., fysiotherapy, material processing, electromechanical sound production, transportation). It is unwanted in many other cases (e.g., earthquake response, human comfort, mechanical wear, induced noise, peak loads, precision manufacturing, precision measurement, structural fatigue). Insight into causes, effects, and remedies of mechanical vibration requires a thorough understanding of basic vibration phenomena. The course introduces the student to mathematical modelling and analysis of the dynamics of elementary mechanisms, structures, and vehicles. It also encourages the student to explore different applications as well as more advanced levels of study in vibration dynamics and control.
Computer use:
PC with MATLAB software.
Laboratory project(s):
In total two sessions of three hours each, to develop experience and confidence with computer-aided analysis of the dynamics of elementary mechanical systems.
Design content:
Throughout the course, system excitation and resulting system response is analysed, and avenues towards redesign of the system for improved performance are discussed.
Percentage of design:
About 20 %
