Problems in the Six-bar Linkage Analysis for Shaper

The displacement formula of ram is differentiated directly,and the velocity and acceleration formulas are obtained.The results of kinematic analysis can be adopted to solve the rotational inertia of fly wheel mounted on the driving crank.The positions of ram presenting the minimal rotational inertia of fly wheel are different from the positions achieving the best loadtransferring stability.Several system parameters also have great influences on the rotational inertia of fly wheel.
