THEORY OF MACHINES II
PRE-REQUISITE : Knowledge in Mechanics
Faculty:Dr. S. Sathyanarayanan
OBJECTIVE: The students will get a clear understanding of dynamic forces acting on machine elements balancing of such forces excitation forces and consequent vibration. They will acquire skills in vibration and force analysis and knowledge of control mechanisms.
1. STATIC AND DYNAMIC FORCE ANALYSIS (5)
Kinetostatic force analysis in mechanisms - Effect of friction at prismatic and revolute joints-- Calculation of crankshaft Torque
2. Fluctuation of energy and speed (7)
mass of flywheel-Function of a governor - to control the speed for varying loads - calculations and determination of initial spring force in spring controlled governors, Effects of friction in governor mechanism
3. BALANCING (8)
Balancing of rotating and reciprocating masses in one plane and in several planes
4. VIBRATION (8)
Longitudinal ,Transverse and Torsional vibration
5. TWO & THREE DEGREES FREEDOM SYSTEMS (8)
generalized coordinates -principal co-ordinates - co-ordinate coupling - Lagrange’s equations - vibration absorbers. Multidegree of freedom systems : Calculation of natural frequencies by Rayleigh, Stodola, Matrix iteration and Holzer methods.
