ME6505 DYNAMICS OF MACHINES L T P C 3 0 0 3
OBJECTIVES:
• To understand the force-motion relationship in components subjected to external forces and analysis of standard mechanisms.
• To understand the undesirable effects of unbalances resulting from prescribed motions in mechanism.
• To understand the effect of Dynamics of undesirable vibrations.
• To understand the principles in mechanisms used for speed control and stability control.
UNIT I FORCE ANALYSIS 9
Dynamic force analysis – Inertia force and Inertia torque– D Alembert’s principle –Dynamic Analysis in reciprocating engines – Gas forces – Inertia effect of connecting rod– Bearing loads – Crank shaft torque – Turning moment diagrams –Fly Wheels – Flywheels of punching presses- Dynamics of Cam- follower mechanism.
UNIT II BALANCING 9
Static and dynamic balancing – Balancing of rotating masses – Balancing a single cylinder engine – Balancing of Multi-cylinder inline, V-engines – Partial balancing in engines – Balancing of linkages – Balancing machines-Field balancing of discs and rotors.
UNIT III SINGLE DEGREE FREE VIBRATION 9
Basic features of vibratory systems – Degrees of freedom – single degree of freedom – Free vibration
– Equations of motion – Natural frequency – Types of Damping – Damped vibration– Torsional
vibration of shaft – Critical speeds of shafts – Torsional vibration – Two and three rotor torsional systems.
UNIT IV FORCED VIBRATION 9
Response of one degree freedom systems to periodic forcing – Harmonic disturbances –Disturbance caused by unbalance – Support motion –transmissibility – Vibration isolation vibration measurement.
UNIT V MECHANISM FOR CONTROL 9
Governors – Types – Centrifugal governors – Gravity controlled and spring controlled centrifugal governors – Characteristics – Effect of friction – Controlling force curves. Gyroscopes –Gyroscopic forces and torques – Gyroscopic stabilization – Gyroscopic effects in Automobiles, ships and airplanes.
OUTCOMES:
TOTAL : 45 PERIODS
• Upon completion of this course, the Students can able to predict the force analysis in mechanical system and related vibration issues and can able to solve the problem
