Mechanical Vibration (ME-7001)
Syllabus UNIT 1: Introduction : Periodical motion, harmonic motion, the vector method of representing vibrations, displacement, velocity and acceleration in harmonic motion, work done in harmonic motion, superposition of simple harmonic motion, beat phenomenon, non harmonic periodic motions. Harmonic analysis System having single degree of freedom, free vibration of systems without damping, Equilibrium and Energy Method for determining natural frequency. Reyleigh’s Method, Equivalent Systems (systems with compound springs, shafts of different diameter Equivalent length, effects of mass of spring and shaft). Free vibration of systems with Viscous, Coulomb and Structural damping. Equations of motion – Discussion of its solutions. Electrical Analogies : Electric circuit principles, equivalent circuits UNIT 2 : Forced vibrations of systems with and without damping (viscous and coulomb), Method of complex algebra, equivalent viscous damping, impressed force due to unbalance, inadmis...
