VIB LAB

This set up has been designed to perform and verify the principles involved in study of vibrations. It consists of a basic frame and various components and sub assemblies designed for quick changeover and easy assembly of number of experiments in vibrations. A speed controller unit is provided for forced vibration experiments.

With this unit following experiments can be conducted –

Pendulum Experiments – For Pendulum a sub frame is attached to upper beam. Two Chucks and Hardened V guide is provided for carrying experiments. 
Experiment - 1 - Simple Pendulum
To verify the relation  and plot graph T² Vs. L 
Experiment - 2 - Compound Pendulum 
i) To verify the relation
ii) To determine the radius of gyration and equivalent length of compound pendulum.
Experiment - 3 - Bi-filler Suspension
( Tortional Oscillations) To determine the radius of gyration of body about the center of gravity by using relation 
Longitudanal Vibration - Experiment - 4 
To verify the relation -
and plot graph T² Vs. W 
Experiment - 5 Equivalent spring mass system
Study of un damped natural vibrations of beam pivoted at one end supported by tension spring at the other end.
Experiment - 6 Equivalent spring mass system
Study of undamped natural vibration of beam pivoted at one end supported by tension spring at the other end to plot a graph of amplitude verses frequency. 
Torsional Vibrations - Experiment - 7 - Single Rotor
To verify the relation -
and study the relationship between the periodic time and shaft length. 
Experiment - 8 - Two Rotor
To verify the relation -
Experiment - 9 Single Rotor with viscous damping -
To find out the damping coefficient Ct for various depths of damping drum (Immersed in oil) and to plot a graph of damping torque Vs. depth of damping drum. Experiment - 10 - Dunkerley`s Rule
To find out the natural frequency of a beam with and without load and to verify the Dunkerley`s Rule Experiment - 11 - Forced Vibrations
To study the forced vibrations for various amount of damping and to plot a graph of amplitude verses frequency. Following accessories will be supplied along with unit. - Exciter unit with FHP motor and controller. Ordinary strip chart recorder. Damper with an arrangement for changing damping.
