MF3012 Design of Machine Elements Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
The main learning objective of this course is to prepare the students for:
• Designing machine members subjected to static and variable loads.
• Designing shafts and couplings for various applications.
• Analyzing bolted and welded joints for various kinds of loads.
• Designing helical, leaf springs and flywheels for various applications.
• Designing and select sliding and rolling contact bearings.
(Use of P S G Design Data Book is permitted)
UNIT I FUNDAMENTAL CONCEPTS IN DESIGN
Introduction to the design process – factor 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 – Design of curved beams – crane hook and ‘C’ frame – Factor of safety – theories of failure – stress concentration – design for variable
loading – Soderberg, Goodman and Gerber relations.
UNIT II DESIGN OF SHAFTS AND COUPLINGS
Design of solid and hollow shafts based on strength, rigidity and critical speed – Design of keys, key ways and splines – Design of crankshafts – Design of rigid and flexible couplings.
UNIT III DESIGN OF TEMPORARY AND PERMANENT JOINTS
Threaded fastners – Design of bolted joints including eccentric loading, Knuckle joints, Cotter joints – Design of Welded joints, riveted joints for structures – theory of bonded joints.
UNIT IV DESIGN OF ENERGY STORING ELEMENTS
Design of various types of springs, optimization of helical spings – rubber springs – Design of flywheels considering stresses in rims and arms, for engines and punching machines.
UNIT V DESIGN OF BEARINGS AND MISCELLANEOUS ELEMENTS
Sliding contact and rolling contact bearings – Design of hydrodynamic journal bearings, McKee’s Eqn., Sommerfield Number, Raimondi & Boyd – Selection of Rolling Contact bearings – Design of Seals and Gaskets – Design of Connecting Rod.
