Abstract

Abstract: Current laboratory tests designed to evaluate package and unit load systems focus strictly on the intensity of vertical orientation. However, due to an increased demand for source reduction and the light‐weighting of packaging components, unit loads are becoming more susceptible to the horizontal forces encountered during transport. Understanding the field measured acceleration levels is critical to developing accurate laboratory test simulations to examine unit load rigidity. This paper uses horizontal acceleration data collected from two air ride suspension trailers to quantify the rise times and steady‐state accelerations levels experienced by the vehicles in the longitudinal (braking) and lateral directions. These characteristics are essential in establishing test methods that accurately reflect field measured events. The results show that the rise times experienced by larger transport trailers are longer than previous reports using smaller trailers. The larger transport vehicles from the present study showed lower decelerations and accelerations in braking and lateral moving events, respectively, compared to smaller transport vehicles. Regardless of travel direction, the deceleration and acceleration levels are right‐skewed, with most of the events falling below 0.33 g. Abstract : Two air ride suspension trailers were instrumented with field data recorders to establish rise times and acceleration thresholds related to braking and turning events. This work presents a way to collect field measured levels for longitudinal and lateral events to aid in establishing test criteria. Results show these events are right‐skewed noting most events are low in acceleration.
