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

Abstract

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.

Influence of an innovative and promising gas clarification process on the quality of stored extra virgin olive oils

“…Several literature studies focussed on the influence of one-parameter stress (such as temperature, humidity, vibrations) on products (Xiang and Eschke, 2004;Chonhenchob et al, 2012;Raghav and Gupta, 2003;Mahajerin and Burgess, 2010). However, contributions that integrate the environmental impacts of food transportation, on-field stress monitoring activity, laboratory simulation and chemical analysis of food products at the place of consumption are lacking.…”

Fastenings Parameters Determination for Highly Deformative Cargo, Taking Into Account Its Durability During Transportation In Cars And Trains

“…The damage boundary, acceleration damage boundary and displacement damage boundary theory for parameter's determining corresponding to the packaging system's working conditions without damage are developed in papers [1][2][3][4][5][6][7][8]. For the first time a damage boundary notion was proposed [1] in order to indicate the structure's sensitivity to the impact or its fragility.…”

“…For the first time a damage boundary notion was proposed [1] in order to indicate the structure's sensitivity to the impact or its fragility. Since the criterion for the damage beginning moment determining is the load maximum acceleration, it is named the acceleration damage boundary [2][3][4][5]. All parameters must be taken into account.…”
