MEC 4306 – Vibration Analysis I
Credits: 4
Lectures/Tut.: 2 hr/wk
Labs: 3 sessions
Prerequisite:
Objectives
An introductory course in Mechanical
Vibration systems having single degree of freedom.
This includes theory, computational aspects and applications. An emphasis of the physical significance and
interpretation built upon previous mechanics units shall be made.
Syllabus
§
Periodic harmonic and
non harmonic motion. Fourier series.
§
Natural frequency of
single degree of freedom systems. The
energy method and Raleigh’s method.
§
Response of viscous
damped single degree of freedom systems due to periodic excitation. Support excitation. Transient
analysis due to impulsive forces.
§
Equivalent viscous
damping applied to single degree of freedom systems.
§
Transverse vibrations
of Beams; Raleigh’s and Dunkerley’s formulae. Beam
inertia. Whirling of shafts.
Laboratory Work
Laboratory sessions include:
§
Response of systems
subjected to forced inputs with and without damping.
§
Development of a
computer program for the solution of a vibration problem.
§
Researched application
assignment.
