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,Review of energy and power expressions,IMPORTANCE OF VIBRATIONS ,
• Modeling issues ,Review of kinematics and generalized coordinate descriptions ,Linear superposition as a “working” principle,MECHANICAL VIBRATIONS AND STRUCTURAL DYNAMIC.

Unit-2:

• VIBRATION UNDER HARMONIC FORCING CONDITIONS,Conservation of energy (first law of thermodynamics) ,
• Lagrange’s equations of class II (holonomic form),Note that the symmetry in the mass, Multiple degree-of-freedom (MDOF) systems ,
• 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.

Unit-3:

• VIBRATION UNDER GENERAL FORCING CONDITIONS,These expressions can be used in conjunction with Hamilton’s principle to derive the EOMs; this technique will not be presented here because it requires a clear working knowledge of variational calculus,Continuous systems of second and fourth-order ,
however, which is beyond the scope of this course.

Unit-4:

• TWO AND MULTI – DOF SYSTEM,Free response of single degree-of-freedom systems for arbitrary damping ,
• Free response of multiple degree-of-freedom systems,Boundary conditions and rigid body modes in semi-definite MDOF systems ,
• Second order continuous systems and separation of variables ,Free response of single degree-of-freedom systems with viscous damping ,
• Principal coordinates and modal transformations,Fourth order continuous systems and separation of variables.

Unit-5:

• Terminology – steady state and transient response ,CONTINUOUS SYSTEMS,Step response: A simple example of forced response analysis ,
• Some review of time-frequency signal representation ,Harmonic response: relative amplitude and phase relationships .
