DESCRIPTION:

The set up is designed to study the whirling of shafts. The set-up consists of a sturdy frame, bearing holders, variable speed motor etc. to drive the shaft along with speed control unit. Different bearing can be fitted in bearing block to have different end conditions i.e.

(i) both end fixed, (ii) one end free and one end fixed etc.

As the test is destructive, hence the shaft can not be used again.

EXPERIMENTATION:

• Display of various modes of whirl for a shaft with :

        a) Both ends directionally fixed.
        b) One ends fixed and other free
        c) Both ends directionally free.

• Modes of vibrations can be studied and frequency can be measured in each case.

UTILITIES REQUIRED:

• Floor area of 2m x 0.5 m.
• Electricity Supply 230 V AC, Single Phase, 0.5 kW.
