ME6503 DESIGN OF MACHINE ELEMENTS
• To familiarize the various steps involved in the Design Process
• To understand the principles involved in evaluating the shape and dimensions of a component
to satisfy functional and strength requirements.
• To learn to use standard practices and standard data
• To learn to use catalogues and standard machine components
(Use of P S G Design Data Book is permitted)
UNIT I STEADY STRESSES AND VARIABLE STRESSES IN MACHINE MEMBERS
Introduction to the design process - factors influencing machine design, selection of materials based
on mechanical properties - Preferred numbers, fits and tolerances – Direct, Bending and torsional
stress equations – Impact and shock loading – calculation of principle stresses for various load
combinations, eccentric loading – curved beams – crane hook and ‘C’ frame- Factor of safety -
theories of failure – Design based on strength and stiffness – stress concentration – Design for
variable loading.
UNIT II SHAFTS AND COUPLINGS
Design of solid and hollow shafts based on strength, rigidity and critical speed – Keys, keyways and
splines - Rigid and flexible couplings.
UNIT III TEMPORARY AND PERMANENT JOINTS
Threaded fastners - Bolted joints including eccentric loading, Knuckle joints, Cotter joints – Welded
joints, riveted joints for structures - theory of bonded joints.
UNIT IV ENERGY STORING ELEMENTS AND ENGINE COMPONENTS
Various types of springs, optimization of helical springs - rubber springs - Flywheels considering
stresses in rims and arms for engines and punching machines- Connecting Rods and crank shafts.
UNIT V BEARINGS
Sliding contact and rolling contact bearings - Hydrodynamic journal bearings, Sommerfeld Number,
Raimondi and Boyd graphs, -- Selection of Rolling Contact bearings.
TOTAL: 45 PERIODS
OUTCOMES:
Upon completion of this course, the students can able to successfully design machine
components
