ME6503 DMM Syllabus, DESIGN OF MACHINE ELEMENTS Syllabus – MECH 5th SEM Anna University

OBJECTIVES

• To familiarize the various steps involved in the Design Process
• To understand the principles involved in evaluating the shape and dimensions of a componentto 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 10
  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 8
  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 9
