Compression Analysis of Primary and Secondary Package

Sammanfattning: The aim of this thesis was to investigate how packages, both primary and secondary, behave under transportation. Before a full analysis of a pallet distribution can be fully understood the understanding of the separate packages is required. This thesis contributes with great knowledge and understanding of how a primary and secondary package behaves during top load compression. Tetra Pak is a global leader in the food & packaging industry and in order to main- tain this market position, continuous investments in new technologies is of great im- portance. Finite Element analysis is one of these technologies which enables more understanding of the manufacturing process and makes faster decision based on well- grounded results possible. This thesis is divided into two parts; Experimental tests and Finite Element Mod- eling, FEM. The experiment is in detailed described, evaluated and discussed using relevant theory, statistical analysis and observations. Several modeling approaches have been reviewed and two nal nite element models is presented. The information collected from the experimental tests in combination with engineer- ing reasoning have contributed to an increased understanding of which parameters are of great importance to capture the physical behavior on a macro-scale. The results from the nite element modeling indicates an modeling approach that capture these behaviors in accordance to the observations and analysis. The result from the work done in this thesis have a foundation for continuous improve- ments. Future difficulties have been highlighted but a workable approach is presented.
