FourBar Mechanism an overview ScienceDirect Topics
The fourbar mechanism is a onedegreeoffreedom linkage The link a is the driving link and therefore the revolute joint connecting it to the base link is selected as the active kinematic pair, this is designated as the generalized coordinate q The angle q defines the orientation of the Roh and Choi (2005) designed an adaptive mechanism composed of two series of Crank MechanismOne of the most common mechanisms: Four rigid bodies: #1 (ground), and three moving bars #2, #3, and #4 Two fixed points: O 2 and O 4 It features one degree of freedom: moving one bar fully determines the position of all other barsFour bar linkage — Machine and Mechanism Theory This article describes the detailed steps in formulating the dynamic equation of a fourbar mechanism in the minimal coordinate form using Lagrangian formulation It is wellknown that Lagrangian Dynamic Formulation of a FourBar Mechanism with
