AE6602 VIBRATIONS AND ELEMENTS OF AEROELASTICITY  LPTC
3003

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
