Abstract:
In the agricultural sector, the loss of stability related to the use of self-propelled agricultural
machinery (SPAM) has caused and continues to cause accidents, often with fatal outcomes. The
probability of occurrence of this risk can be reduced by acting on various aspects, but above all the
presence of a protective structure is necessary. Depending on the machine, the protective structure
can be a roll-over protective structure (ROPS), or a tip-over protective structure (TOPS). Hence, to
reduce this gap, a reverse engineering approach and virtual engineering methods were applied
starting from the analysis of harmonized standards actually in force, with the goal of providing both
a reference procedure to be used in the risk assessment analysis of SPAM’s protective structures and
technical information to manufacture and install protective structure on old agricultural machinery.
Two representative case studies were used to validate the procedure by means of finite element
method (FEM) analyses and computer aided design (CAD) prototyping. Results show that the
proposed approach can represent a useful indication for the safety update of this type of machinery.
