- 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 .
