| Abstract: | The general formula of the motion specifications of a cam mechanism follower can satisfy the needs of different selection of motion specifications for the low, medium, or high speed cam mechanism. Using the general formula of the motion specifications of a cam mechanism follower, the design of cam profile is advanced which uses several segments curve to optimistically fit the profile of the cam whose follower has special motion requirement. Furthermore, the dynamic performance of the cam mechanism is ensured to be satisfied. The comprehensive optimization of the kinetic and dynamic performance of cam mechanism is achieved. |
