Question
1. The two parts in Figure P6.1 are to be mated together as shown. Using only the features labeled, apply assembly constraints to mate the two pieces so that the top part is fully constrained and assembled correctly with the bottom part. Assume the bottom part is already fixed in position. Specify five ways of doing that using only coincident and concentric constraints. An example follows: Constraint set 1: hole 1 concentric with hole 2 surface 1 coincident with surface 3 surface 2 coincident with surface 4 Surface 4 Hole 2 Cylindrical surface 2 Assembled Surface 1 Surface 3 Hole 1 Edge 2 Edge 1 Cylindrical surface 1 Surface 2 2017 Cangage Learning Courtesy of D. K. Lieu. FIGURE P6.1. Constrain the edges and surfaces of (a) to create the assembled position (b).Explanation / Answer
Constraint set 1
-Cylindrical surface 1 concentric with cylindrical surface 2
-Surface 2 coincident with surface 4
Constraint set 2
-Edge 1 coincident with edge 2
-Surface 2 coincident with surface 4
Constraint set 3
-Cylinderical surface 1 concentric with cylindrical surface 2
-Hole 1 concentric with hole 2
Constraint set 4
-Edge 1 coincident with edge 2
-Hole 1 concentric with hole 2
Coinstraint set 5
-Hole 1 concentric with hole 2
-Surface 1 coincident with surface 3
-Surface 2 coincident with surface 4
