The pallet load composed of carton boxes takes various stabilizers on distribution. The vibration tests can be taken as the way of evaluating the effect of the pallet load stabilizers. However, no confirming test protocols of the load stabilizing efficiency have been existed, because non-determinative motions are happened on the each box even if in the sinusoidal vibrating condition. First of all, the new reliability rate of the pallet load stability is proposed. The indoor falling down vibration tests of the pallet load strapped by the reusable belts are carried out to identify stabilizing effect. And the mathematical model by the distinct element method is produced to calculate the movement of the pallet load falling down in vibration. Some basic vibration tests using the stacking blocks are also carried out to confirm the mathematical model.
