The objective of this paper is the highlighting of the main aspects that be considered in numerical simulation of the behavior of roll-over protective structures that are included in mobile machinery cabs, using finite numerical simulation. In first part of the paper are presented, briefly, the legislative framework and the reference documents governing the mechanical protection of the human operator of machinery and equipment construction. Next, are analyzed the roll-over protective structures and the main aspects related to their evaluation by shock loading simulation. In this context, are given the necessary information to correctly model the real problem so that the results to have an imposed accuracy. |
