Analysis and Optimization of the Transmission Angle of Crank Rocker Mechanism

摘要

In view of the quick return characteristics of I and II type crank rocker mechanism, the inner relationship between the size of components is analyzed. The parametric model of mechanism is established based on ADAMS software, then, with the minimum transmission angle to take the maximum as the optimization goal, lists the objective function and constraint equations of I and II type crank rocker mechanism. With the established model, the optimization of the structure parameters is proposed to recover the maximum value of the minimum transmission angle. By the optimization, the minimum transmission angle of mechanism get a great improvement, this result can effectively improve transmission efficiency of the mechanism.
