In this research, we have developed a design method to synthesis and analyze high speed dwell-rise-return-dwell (D-R-R-D) cam follower system.  With its general and systematical characteristics, it becomes a superior design tool for cams.

To synthesis the follower motion curve, we use the B-Spline function to interpolate the motion constraints.  When the cam is working at high speed, the follower will not be a rigid body. We use a one-degree of freedom(DOF) lumped-parameter model to simulate the follower’s dynamic characteristics. According to the motion equation at the designed speed, by using B-Spline collocation method to solve this ordinary differential equations(ODE).  We have solved the cam profile that can generate the follower motion curve and tested follower’s dynamic characteristics at different speeds.

With the use of the proposed procedure, we can design a high speed cam with excellent static and dynamic characteristic performance. Those results are discussed and compared with traditional polynomial and polydyne cams in this research.
