To propose potential lab-simulated vibration tests for developing appropriate cushioning packaging, we recorded vibration acceleration during truck transport, including large sporadic shocks in regular smaller vibration so that acceleration did not cover a normal probability distribution and could not be considered as random vibration. We extracted all shock acceleration from vibration during local road and highway transport and studied the causes. We found that shocks were caused by road roughness, metal joints, difference in levels on the asphalt-surfaced road, pedestrian crossings, manholes, road curves, left and right turns, railroad crossings, etc. After removing shock events from all vibration acceleration during transport, we reconstructed remaining acceleration as continuous vibration. Vibration acceleration followed the normal probability distribution and could be considered random.
