Abstract

Courier express parcel (CEP) shipments become one of the most important delivery methods in the Business-to-Consumer sales model. This paper observed and analyzed the vertical vibration levels that occur in stacked and unsecured parcels during express delivery versus the simulation in the laboratory. At the end, a detailed comparison is reported between the field and laboratory vibration levels (based on standard PSD test profile) in the frequency range of 1 – 200 Hz. For the measurement a three-layer stacked unit was used building from corrugated box samples. The result shows and analyzes the vibration levels in the stacked layers in comparison to the ISTA (International Safe Transport Association) vibration protocol where only a single parcel is required to be tested without any stacking configuration.
