Design of a 5th-polynomial high speed cam-based intermittent four-bar linkage mechanism

With the higher demands of speed and accuracy for automatic mechanism, the diversified parameters and kinematics issues have been paid much more attention in the field of cam research. This paper introduced a special cam-based intermittent linkage mechanism that would produce an ideal application in high speed motion. On the basis of analyzed and compared the basic standing kinematics cam curves, from the point of view of kinematic characteristic, analysis the curve characteristic (the units of kinematics eigenvalue, such as displacement, speed, acceleration and so on), the 5^th polynomial profile curve is established. In this paper, kinematic analysis of this cam-based linkage mechanism was done by separate the system into two parts for its one kind of closed-chain structure.
