SINGLE ROTOR SYSTEM /TORSIONAL VIBRATION/ EXPERIMENT

This video are types of vibration basically torsional vibration single rotor system system.In this experiment one end of the shaft is gripped in the chuck and heavy flywheel free to rotate in ball bearing is fixed at the other end of the shaft. Thus length of the shaft can be varied during the experiments.The torsional vibration of the crankshaft forces the fluid through narrow passages that dissipates the vibration as heat. This type of damper reduces the vibration at specific engine speeds when an excitation torque excites the first natural frequency of the crankshaft, but not at other speeds.

Sir ur not considering units in calculation .....
So calculation are may be wrong

Very nice...

Torsional stiffness Kt calculation is wrong, you taken G = 9.81 wheres the G = 0.86x10⁶ kg/cm². So G means modulus of rigidity not gravity.

👍

[@dr.arvindkumar3572]

In calculating torsional stiffness you have taken L in centimeter i.e 50 while J(which you r saying it remain constant,i.e 7) you have taken shaft/wire in mm i.e 3mm, why?

G is not equal to g =9.81 . Galat video upload mat karo
