Modelling of the effects of continual shock loads in the transport process

In the transport process, continual shock loads are typical stresses for packaged products. The studies of the effects of continual shock loads were performed on test specimens in the laboratory. The findings of these studies were used to deduce the relationship between acceleration amplitude and the number of continual shocks to failure, and a corresponding mathematical model was developed. On the basis of the individual mathematical models for the products tested, two further models were proposed for all products. This makes it possible to arrive at a better assessment of the fragility of different product types when exposed to continual shock loads. These models are capable of producing substantial cost reductions in the design of packages, as they allow the cushioning to be tailored more precisely to the fragility of the products.
