Torsional vibrations of camshafts
Mechanism and Machine Theory, 1992 Abstract This study deals with the torsional vibrations on the camshafts in force closed cam mechanisms. On the cam mechanisms with reciprocating followers, the variable torque which is produced by force exerted to the cam from the follower, will create torsional vibrations on the camshaft.
