Note :- These notes are according to the R09 Syllabus book of JNTU.In R13 and R15,8-units of R09 syllabus are combined into 5-units in R13 and R15 syllabus. If you have any doubts please refer to the JNTU Syllabus Book.

Unit-1:

  • 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.

Unit-2:

  • 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.

Unit-3:

  • 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.

Unit-4:

  • 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.

Unit-5:

  • 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 .
