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
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
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
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.
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.
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.
