WebDec 26, 2024 · In this tutorial we will learn how four bar linkages work. We will create and assemble these linkages in SOLIDWORKS. I will describe crank rocker mechanism (one complete revolution) and double crank mechanism (two complete revolutions). These four linkages are: 1) Fixed Link or Ground Link (q) 2) Shortest Link or Crank (s) WebNov 5, 2012 · The four-bar linkage of this Demonstration has four joints () and a total of four links ( ), of which one is grounded ( ). According to Gruebler's equation for planar mechanisms [2], the number of degrees of freedom is . The Freudenstein equation [3] is used to compute the kinematics of a four-bar linkage.
