CROP Flatrack on 463L “Triple
Married Pallets” on K-Loader Roller Bed
MechSim used finite element analysis to predict the load distribution for a
loaded CROP platform sitting on three flexible 463-L pallets, sitting on a
bed of uneven K-loader rollers. The images below show CROP geometry and
rails, a 463L pallet (aluminum skin on balsa core), NASTRAN FEA mesh, and the
resulting predicted roller load distribution.

Boeing TSV Cargo Handling System
- Restraint Track Analysis
Mechsim used traditional FEA analysis to facilitate successful design of the
cargo handling system employed on the new Army TSV ships. The tracks
are welded to the deck and the restraint rails and locks lock into place with
high-strength tabs. The first image shows a section of track, rail, and
two locking devices. The second image shows a cross section of the
track and rail with loading conditions. The third image shows the loads
transferred to the track and the final image shows a typical stress contour
plot for the track.
