Abstract
This paper presents a defect-free analytical synthesis of four-bar linkage for four precision positions using the proposed algorithm. The proposed algorithm poses several constraints such as extremity of transmission angle, Grashof conditions, and the minimum perimeter condition, to obtain a defect-free and compact four-bar linkage. Besides these constraints, one more constraint is applied which keeps the moving pivot of driving link outside the wedge-shaped region, which is consistent with the Filemon’s construction. This constraint ensures that mechanism has no circuit defect. In this work, motion generator mechanism is synthesized by considering four precision positions. This work proposes an algorithm named as perimeter algorithm, and a realistic example is considered to demonstrate the effectiveness of the algorithm.
