Some vibration‐based damages in packaged products, such as surface abrasion and bruising of fruits, are not necessarily caused by vibration stresses at resonant frequencies. They are often nonfatigue damages resulting from the accumulation of low stress vibrations. This study introduces a new concept and methodology of vibration damage rate curves, which describes the relationship between damage rate, G rms , and vibration cycles, N . The vibration damage rate curves for quantifying the abrasion of a column stacked printed packaging was developed on the basis of ASTM D 4169 truck profile level 1, 2, and 3, as well as the field test. The abrasion rate in the laboratory was then compared to that in the equivalent time of road transportation per accelerated random vibration test formula. This study recommends that the accelerated random vibration formula can be used when vibration damage rate curves for printed packaged products are developed, to effectively reproduce the damage in the laboratory that is equivalent to the field.
