Clevis Design and Sims
Design Overview
Sim Setup Explanation
Take the 24_DYN_3101 NARRCO Rack Assembly file and hide all components except:
Rack Shaft (A body in the NARRCO Rack Part Assemby file)
All bodies in the clevis part file
Both of the DL-90128A634-McMaster (0.375-16x2.5 SH) parts
Create a Static Structural System in ANSYS
Engieneering Data (From Min_Materials)
4130 Steel Normalized
7075 T6 Aluminum
6061 T6 Aluminum
Geometry
