Introduction to Mechanical Vibrations,,MECHANICAL VIBRATIONS AND STRUCTURAL DYNAMIC,Modeling issues ,Linear superposition as a “working” principle,Review of kinematics and generalized coordinate descriptions ,IMPORTANCE OF VIBRATIONS ,Review of energy and power expressions.
VIBRATION UNDER HARMONIC FORCING CONDITIONS,Newton’s second law and Euler’s equation, damping, and stiffness matrices has disappeared and the
coordinates have become dynamically coupled as well as statically coupled,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.
VIBRATION UNDER GENERAL FORCING CONDITIONS, 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,Continuous systems of second and fourth-order ,These expressions can be used in conjunction with Hamilton’s principle to derive the EOMs;
TWO AND MULTI – DOF SYSTEM,Free response of multiple degree-of-freedom systems,Principal coordinates and modal transformations,Boundary conditions and rigid body modes in semi-definite MDOF systems ,Free response of single degree-of-freedom systems for arbitrary damping ,Second order continuous systems and separation of variables ,Fourth order continuous systems and separation of variablesFree response of single degree-of-freedom systems with viscous damping.
CONTINUOUS SYSTEMS,Harmonic response: relative amplitude and phase relationships,erminology – steady state and transient response ,Some review of time-frequency signal representation ,Step response: A simple example of forced response analysis.
