A Design Study in Ductile Iron - Dotson Company Pivot Frame

Design Iterations

The design team developed three designs and used FEA to evaluate and optimize the stresses in the trapezoidal support frame (where stresses were highest). 

Design A
Plate with Perimeter Ribs
Design B
Frame with Cross Ribs
Design C
Plate with Ribs and Cut-Outs
Choose the design (A, B, or C) which will meet the maximum stress requirement and give the lowest overall weight.
