  1. Design and Structural Analysis of the Modular Pallet System Developed for Container Roll In/Out Platform (CROP) Principal Investigator Dr. M. C. Altan Undergraduate Assistants Brad Williams and John Byers School of Aerospace and Mechanical Engineering University of Oklahoma April 2005

  2. Project MotivationImprovement of a Loaded Container Roll In/Out Platform (CROP) Current Obstacles • Technical and time consuming packing methods • Battlefield clutter • Wood importation restrictions • Non-reusable wood pallets and packaging

  3. Project Objectives • Detailed design of a modular pallet system used for ammunition transport • Achieve flexible design to accommodate multiple loading configurations • Development of a finite element model for structural analysis • Structural analysis of the assembled modular pallet • Analysis of stress distribution and deformation induced under various loading

  4. Project Activities • Convert existing concept design into a Pro/E model • Prepare engineering drawings with detailed dimensions • Consider potential materials and manufacturing methods • Review possible prototyping • Finite element structural analysis: • Stress state under various loading conditions. • Deformation characteristics under various loading conditions.

  5. Modular Pallet Information • A single module has only three different parts: • One Pallet Top • One Pallet Bottom • Four Identical Pallet Sides • Each module can assembled and disassembled completely without any tools. • Modular pallets are completely reusable, minimize battlefield clutter. • Parts are stackable upon disassembly: • This allows for efficient shipment of empty pallets. • Once a pallet is disassembled, its top, bottom, and four side walls can be stacked and strapped to the CROP. • Multiple disassembled modules can be shipped easily.

  6. Modular Pallet Information • All single pallet modules are identical, thus the same sliding assembly method is used for all. • Slide-in panels are used to create compartments. • Each pallets module can be subdivided into eight smaller compartments. These compartments make the pallets more versatile in the types of munitions they can carry. • Side and vertical locking eliminates strapping and complications arising from end loads such as chimney stacks. • Side interlocking system is used. The two adjacent modules are interlocked at the pallet bottom. • Self-locking vertical interlocking system is used.
