Finite element analysis of cam and its follower contact stress mechanism

Camshaft can be defined as a machine element having the curve outlined or a curved grooved, gives the predetermined specified motion to another element called the follower. In automotive field, Camshaft and its follower take importance roles to run the engine. Nowadays the car maker have developed...

The finite element analysis are done for determination of stress concentration during 30 degree of cam where the roller fully climbing the cam and during maximum exhaust valve lift.
