    Understanding Forklift Vibration for Pre-Shipment Testing: Insights and Recommendations , article

    In the complex world of distribution, ensuring the safe delivery of products depends heavily on the ability of packaging systems to withstand the physical stresses encountered during transportation. One critical factor that affects product integrity is vibration. Whether products are being moved via trucks, railcars, or forklifts, the vibrations during transport can pose significant risks to packaged goods. Understanding the vibration environment during distribution is therefore essential to designing packaging systems that can protect products from damage. This article delves into the findings of CPULD’s graduate student, Yu Yang Huang’s study aimed at measuring and analyzing vibration levels during forklift handling and its implications for pre-shipment testing. The purpose of Huang’s study was to analyze the average vibration levels generated by forklifts and to provide insights that can be used for pre-shipment testing of packaging systems. By accurately simulating the vibration environment that occurs during forklift handling, packaging engineers can better assess the durability and suitability of their packaging systems.

    Investigating the Impact of Pallet Design on Plastic Pail Performance , article

    Palletized unit loads are fundamental to the supply chain. These distribution systems, composed of pallets, packaging, and unit load stabilizers, play a critical role in ensuring the safety and efficiency of logistics operations. While significant research has been conducted on corrugated boxes used in palletized loads, the behavior of plastic pails under similar conditions has remained largely unexplored. Plastic pails, widely used for transporting various liquid and solid materials, introduce unique challenges due to their structural characteristics and load distribution behavior. CPULD’s graduate student, Mary Paz Alvarez, conducted research focused on the interactions between plastic pails and pallet components, particularly the effects of pallet top deckboard thickness and pail location, with the aim of improving pallet design for safer and more sustainable transport of pails.

    Exploring the Durability of Wooden Pallets: Insights from the Field and FasTrack Simulation Testing , article

    The durability of wooden pallets is a critical factor in determining their overall performance and longevity within supply chains. As pallets are subjected to repeated handling and transportation, their ability to withstand wear and tear directly impacts their usefulness and, ultimately, supply chain efficiency. Predicting the durability of pallets offers valuable insights into potential maintenance costs, replacement schedules, and environmental impacts through the reduction of waste. CPULD’s graduate student Jorge Masis conducted research to correlate the damages observed in wooden pallets used in real-world conditions with those observed in controlled testing using Virginia Tech’s FasTrack simulation. By subjecting pallets to controlled, repeatable conditions, FasTrack allows researchers to replicate and predict the damages that might occur over the lifespan of a pallet.
