Introduction to Mechanical Vibrations,IMPORTANCE OF VIBRATIONS ,Modeling issues ,Linear superposition as a “working” principle,Review of kinematics and generalized coordinate descriptions ,Review of energy and power expressions ,MECHANICAL VIBRATIONS AND STRUCTURAL DYNAMIC.
VIBRATION UNDER HARMONIC FORCING CONDITIONS,Newton’s second law and Euler’s equation,Conservation of energy (first law of thermodynamics) ,Lagrange’s equations of class II (holonomic form),Multiple degree-of-freedom (MDOF) systems ,Note that the symmetry in the mass, damping, and stiffness matrices has disappeared and the
coordinates have become dynamically coupled as well as statically coupled.
VIBRATION UNDER GENERAL FORCING CONDITIONS,Continuous systems of second and fourth-order ,These expressions can be used in conjunction with Hamilton’s principle to derive the EOMs;
however, this technique will not be presented here because it requires a clear working knowledge
of variational calculus, which is beyond the scope of this course.
TWO AND MULTI – DOF SYSTEM,Free response of single degree-of-freedom systems with viscous damping ,Free response of single degree-of-freedom systems for arbitrary damping ,Free response of multiple degree-of-freedom systems,Principal coordinates and modal transformations,Boundary conditions and rigid body modes in semi-definite MDOF systems ,Second order continuous systems and separation of variables ,Fourth order continuous systems and separation of variables .
CONTINUOUS SYSTEMS,Terminology – steady state and transient response ,Some review of time-frequency signal representation ,Step response: A simple example of forced response analysis ,Harmonic response: relative amplitude and phase relationships .
