Syllabus:

Natural and Forced Vibrations - Spring-mass systems, 1, 2 and multi degree of freedom, correction for mass of spring, modal shape, viscous damping, damping ratio, logarithmic decrement, force, inertia and base displacement excitation: dynamic magnifier, resonance, phase, transmissibility. Torsion vibrations - Torsional stiffness of variable cross-section shafts, torsional oscillations with multiple rotors, geared systems, circular bar in torsion. Beam vibrations - Euler-Bernouli beam, transverse vibration of beams with distributed mass, beams with concentrated masses, whirling of shafts. Vibration Measurement - Transducers and vibration specifications.

Unit Outcomes:

On successful completion of this unit students will have achieved an introduction to the fundamental concepts and the systematic study of dynamics of mechanical vibrations of both lumped parameter and continuous systems including their mathematical models. They will also have gained an understanding of which vibration modes are applicable to given machinery or structural configurations and have been introduce vibration measurement and analysis techniques.
