DYNAMICS OF MACHINERY

Course Objective:

In this period of modern technological development one cant deny the importance of

various machines and machine components. Machines and machine components areused in very small scale industrial units like road side flour mills, general purpose

engineering workshop to complex applications like aviation, nuclear, oil refineries etc . In

all these applications the fundamental parts are machine components that are

assembled together for a specific engineering purpose. The relative position of different

links (i.e. parts of engineering machine for example I.C engine piston and connecting rod)

the size and shape of different links will dictate the relative motion of the parts. Which in

turn affects the output of an engine or machine? This subject of dynamics of machinesessentially deals with different forces acting on the machine (including inertial forces) and

their effect on the machine components.

This subject is divided in to eight units.

First unit deals with the concept of gyroscopic couple which is useful in confirming the

stability of 2-wheeler, 4-wheeler automobiles, aero planes, ship etc. This simple concept

of gyroscope is used in making the satellite to revolve round the earth in a fixed orbit,

pistols used for precessional aiming of targets etc.


23/55

Unit II & III deals with analysis and synthesis of mechanism. Synthesis of mechanism

requires determining the lengths of various links that satisfy the requirement of

displacements , velocities and accelerations of various links of a machine. Both analysis

and synthesis are useful in obtaining desired relative motion for a specific engineering

purpose like motion of automobile, operations of lathe machine etc.

Unit IV deals with brakes, clutches and dynamometer. Brakes and clutches are the

necessary components found in automobiles. In this chapter different types of brakes

and clutches and calculation of frictional torque requirements etc. are dealt. Different

types of transmission and absorption dynamometers are discussed.

Fly wheel is the general component found in I.C. engine. It acts as a reservoir of energy

by virtue of inertia. It absorbs the energy when engine is providing more energy and

gives out energy to engine whenever it is required. Computation moment of inertia of

flywheel, rim dimensions etc for a given fluctuation of energy and speed are dealt in this

chapter. Flywheel for a punch press is also discussed.

One of the important components of I.C. engine is governors. Governors are useful in

nullifying speed fluctuation caused by variation of load. Different types of governors are

discussed in this unit.

In every machine, the basic concern is vibrations. The goal of every design engineer is to

minimize the vibrations. Major cause of vibrations is imbalance. These two aspects are

covered in unit VII and unit VIII .Unit VII concentrates on different methods of balancing

of multi cylinder in line engine and v-engines

Unit VIII concentrates on different types of vibrations i.e. longitudinal, transverse and

torsional vibrations and methods of determining natural frequency. Vibration isolation and

transmissibility are also discussed in this unit.

To summarise, studying dynamics of machines is highly useful to us in analyzing the

forces acting on different machine parts and effective utilization of these forces while

minimizing the magnitude of unwanted forces. Basics of engineering mechanics are

essential to solve the problems. This subject consists of 80% numerical problems and

20% theory. This subject will sufficiently ignite the analytical capabilities of mechanical

engineering students.

MACHINE TOOLS

Course objective

Machine tools is one of the important subject in mechanical engineering faculty, not only

in educational institutional, but it has very much of importance in industrial domain.

Without a machine tool, there is no industry.

A source of power is always needed in various workshop processes particularly in cutting

and forming of metal in a machine tool. In the metal-working industry work pieces of most

different shapes and dimensions and of different materials are worked. In every industry

we need shaping of materials. This shaping of materials is done by either non-cutting

process or cutting process. For example forging, pressing, drawing, etc are non-cutting

shaping processes. Turning, drilling, mailing etc are comes under cutting shaping

operations. The process of metal cutting in which chip is formed is affected by relative

motion between the work piece and the hard edge of a cutting tool held against the work

piece. Such relative motion is produced by combination of rotary and translating

movements either of work piece or the cutting tool or of both.

Machining process also include other processes like grinding, slotting, shaping, honing,

planning, lapping, and broaching operations.

After completion of the machine tools course, students can be able to identify various

applications of different tools, can be able to differentiate various tools for different

machining operations, and also they can be able to solve many industrial problems

regarding machine tools. And also as the kinematics of machines studied, students can

be able to design various machine tools for various machines.

students will be presented with design challenges. The type of design addressed in

this course is that of detailed design, which is to define the shape, size and material

of a particular machine element such that it will not fail under the expected load and

operating conditions. .
