About the parametric modelling of the protective structure included in a tractor cabin in order to study its protective capability using the finite element method

Abstract

The objective of the paper is the highlighting of the main aspects that are considered in parametric modelling of the protective structures included in a tractor cabin in order to study its protective capability, using finite element method. In the first part of the paper are presented, briefly, the main reference documents governing the mechanical protection of the human operator working on an agricultural tractor or forestry tractor. Also, it is presented the algorithm used in optimization process of the protective structures using CAD and FEA platforms. Next, it is presented a parametric analysis of the protective structure included in a tractor cabin, in order to determine the main geometric parameters characterizing such structures. These geometrical parameters are used in a case study where the geometry for a protective structure was generated using a CAD platform. In the final part of the article conclusions are presented.
