Four-Bar Linkage Design Using Global Optimization Approach
The paper discusses optimal synthesis of the four-bar mechanism. The general optimization problem is addressed in the form of nonlinear programming problem. The objective of this approach is to determine the optimal values of the mechanism link lengths, to minimize the hinge loads, while the difference between the prescribed trajectory and the trajectory of the arbitrary point on the mechanism coupler link has to remain within the prescribed range. A global optimization method is used in order to find the global optimal solution. The procedure uses the Adaptive Grid Refinement algorithm.
