Influence of Shocks on Pallet Load and Cargo Securing

Abstract

The paper deals with an evaluation of the transport experiment on D1 highway with Tatra T-815-7. The goal is to analyze the magnitude of shocks affecting the cargo during the transport with the emphasis on safety. Evaluated data was collected from three equal rides with the usage of 3-Axial Accelerometer with datalogger positioned on the fastened metal pallet in the center of the cargo space. The evaluation was performed with the usage of measured shocks (acceleration coefficients) in individual axis of descriptive statistics. The results of the analyses show somewhat significant deviations from normatively set acceleration coefficient values, especially in axis z. Despite rather a modern vehicle, drive on a highway in higher speed leads to frequent exceeding of normatively set limits, as per EN 12195-1:2011, having so a direct impact on cargo securing. The article also includes illustrative calculations of necessary securing forces for extremes in measured values and verification of used securing system parameters.
