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) 3) Longest Link or Coupler (l) 4) Remaining Link or Rocker (p) I have explained Grashof's principle on which these linkages work. s + l ≤ p + q I have also shown few examples. Some are: 1) Bicycle 2) Wiper Mechanism 3) Door Mechanism 4) Oil Well Pump 5) Locking Plier 6) Suspension Mechanism We will assemble these using simple mates (coincident and concentric). After assembling these link we will perform motion study in SOLIDWORKS Motion Analysis. We will give input at crank (20 rpm) and see the response on the output link (p). It is a good exercise for beginners and it will be a good practice for beginners. Kindly use play pause technique for practice. I have attached files in t
