OBJECTIVES:

• To study the effect of time dependent forces on mechanical systems and to get the natural characteristics of system with more degree of freedom systems.
• To study the aeroelastic effects of aircraft wing.

UNIT I	SINGLE DEGREE OF FREEDOM SYSTEMS	10

Introduction to simple harmonic motion, D’Alembert’s principle, free vibrations – damped vibrations – forced vibrations, with and without damping – support excitation – transmissibility - vibration measuring instruments.

UNIT II	MULTI DEGREES OF FREEDOM SYSTEMS	10

Two degrees of freedom systems - static and dynamic couplings - vibration absorber- principal co- ordinates - principal modes and orthogonal conditions - eigen value problems - hamilton’s principle - lagrangean equations and application.

UNIT III	CONTINUOUS SYSTEMS	8

Vibration of elastic bodies - vibration of strings – longitudinal, lateral and torsional vibrations

UNIT IV	APPROXIMATE METHODS	9

Approximate methods - rayleigh’s method - dunkerlay’s method – rayleigh-ritz method, matrix iteration method.

UNIT V	ELEMENTS OF AEROELASTICITY	8

Vibration due to coupling of bending and torsion - aeroelastic problems - collars triangle - wing divergence - aileron control reversal – flutter – buffeting. – elements of servo elasticity

TOTAL : 45 PERIODS

OUTCOMES:

• Gaining understanding of single and multi degree vibrating systems
• Ability to use numerical techniques for vibration problems
• Knowledge acquired in aero elasticity and fluttering
