WebFeb 1, 2008 · Higher values of acceleration and jerk of the cam follower of a cam driven system are never desirable as these affect smoothness of operation of the system and generate force that induces high contact stress on the cam surface. Higher the contact stress, higher is the surface fatigue, which damages the cam-surface. WebJan 1, 2009 · Therefore, the design of cam mechanisms must consider elastic deformation at high speed. Generally, the three main components of a cam mechanism are: a cam (the driving element); a...
