Machine design occupies a prominent place in Mechanical Engineering and it‘s most indispensable tools are the information resources available in the form of standards, codes research results etc.  to develop new or improved machines. This course is designed to fulfil this requirement.

In this course the students will be acquainted with standards, safety, reliability, ergonomic statistical considerations and manufacturing aspects in mechanical design. The topics dealt in the course and the pedagogy is aimed to prepare the graduates with the ability to analyse and design various machine elements to meet the needs with in realistic constraints. 

The students  will  be able to apply  fatigue  failure  criteria  in the analysis  and  design of mechanical components. The students will be able to analyse and design power transmission shafts carrying various elements with geometrical features. At the end of this course, students will be able to analyse and design mechanical springs, rolling element bearings, hydrodynamic journal bearing, hydrostatic thrust bearing and selection of lubricants. The students will be able to analyse and design the spur, helical, bevel and worm gear. Through this course, students will also be able to improve their technical report writing skills.

The  topics covered are as under:
  • Ergonomic and value engineering considerations in design
  • The influence of manufacturing processes in the design of machine elements
  • The stress concentration due to geometric discontinuities present in machine elements
  • Various fatigue failure criteria, load-life relation and finite and infinite life of machine components
  • To apply fatigue failure criteria in the design and analysis of machine components under various loading conditions
  • Spring terminology and different types of springs
  • To design and analyze coil springs (compression, tension, torsion) under various loads
  • The function of bearing, types and load- life relationships
  • To select the bearing from catalogue for a given application
  • The  basic modes of lubrication in journal bearing
  •  To analyse and design hydrodynamic journal bearing based on temperature rise and other specific parameters
  • Types of gears and application, force acting on gear tooth and common types of failure
  • To analyse and design the gears based on beam strength, dynamic loading and wear
  •  To justify a design project in a formal report
  • To perform and present design calculations in a neat and organized manner etc.

Preamble:

A very important aspect of the dynamic behavior of a system is: when a (finite) input change is implemented on a physical system, does the resulting transient response ultimately settle to a new steady state, or does it grow indefinitely? If it is indeed possible for a dynamical system not to settle eventually to another steady state, but have its output grow indefinitely when disturbed from an initial steady state, what characteristics of the system determine whether or not such behavior will occur? This course is primarily concerned with investigating those issues having to do with the stability properties of linear dynamical systems.

Course Outline:

  • Introduction and Origin of Stability Analysis
  • Routh-Hurwitz Criterion and Analysis
  • Stability analysis using Root-locus method
  • Nyquist Stability Criterion and Analysis
  • Stability Margins
  • Relative Stability
  • Input-Output stability
  • Stability in the Presence of Uncertainty

The main course contents are: Flynn 's,  classification, conditions of parallelism,  sharing of memory between multiple processors,  various hazards due to pipeline,  von Neumann and non von Neumann architecture,  Risc and Cisc arch., scalar,  superscalar,  pipelined,  super pipelined and superscalar superpipipelined, numa,  coma and message passing etc.
