VIBRATIONS OF A BOX OF PACKAGES EXCITED BY NON-UNIFORMITIES OF THE ROAD PROFILE
Eigenmodes of ten rows and ten columns of packages in a box are analyzed. A package is represented as a single plane strain element. Interconnection of packages is assumed by special elements which ensure continuity of the normal displacement by the penalty method.
Eigenmodes of ten long packages in a box are analyzed. A long package is represented as consisting from ten plane strain elements.
The influence of vibrations in the process of transportation of packages is analyzed by taking the non-uniformities of the road profile into account. The main structure of the performed investigation is presented here, while the detailed optimal synthesis and results of experimental investigations are the subjects of other papers.
