Effect of Flexibility of Driving Shaft on the Dynamic Behavior of a Cam Mechanism

The flexibility of the driving shaft affects the dynamic behavior of a cam mechanism. On the basis of a dynamic model this effect can be determined theoretically. The results of different dynamic models are then compared with test results. The drawing up of rules concerning the design of cam mechanisms makes use of a model which is sufficiently accurate as well as sufficiently simple, so that the dynamic response can be characterized by merely two dimensionless parameters, one for the follower and one for the camshaft.
