Resumo
A atividade do setor agrícola é uma das mais importantes para economia mundial, responsável por suprir demandas em uma infinidade de áreas, de forma direta ou indireta, no que se refere ao consumo humano. Os tratores por serem muito versáteis, são utilizados como uma das principais ferramentas deste meio, que possibilitam o ganho de força e velocidade na execução de trabalho. Embora os tratores tragam tantos benefícios ao meio agrícola, existem uma série de cuidados que devem ser rigorosamente seguidos para a preservação da vida do condutor durante a utilização da máquina. Muitas vezes o trabalho é realizado em solos irregulares, com muitos aclives e declives, tornando assim a atividade perigosa e propiciando acidentes por tombamento laterais, entretanto, a operação com tratores em solos declivosos é considerada pertinente em muitas situações. Em uma pesquisa rápida, é fácil encontrar notícias recentes sobre acidentes envolvendo tombamento lateral de tratores e, considerando que muitos desses casos não são contabilizados pelas autoridades locais por ocorrerem em regiões afastadas, conclui-se que a ocorrência desses acidentes é mais frequente do que se imagina. Com o avanço das normas regulamentadoras no que se refere a segurança do indivíduo ao executar sua atividade, os fabricantes de tratores atualmente têm uma preocupação maior com a segurança do trabalhador, através da adaptação e desenvolvimento de sistemas de segurança que protegem o condutor durante o tombamento. Hoje em dia o sistema de segurança que é obrigatório definido na Norma Regulamentadora 31 (NR31), se resume em estruturas de proteção em caso de capotamento e cintos de segurança, que não previnem o acidente, entretanto podem diminuir sua gravidade. Tendo em vista todos os aspectos citados, é proposto desenvolver um conjunto capaz de prevenir tombamentos laterais em tratores agrícolas, reduzindo assim acidentes com invalidez e, ou, fatais através do Controle auxiliar do sistema de direção que possibilite a realização de esterçamento quando identificado risco de tombamento lateral em tratores agrícolas apoiado em simulações com os softwares Matlab e Siemens NX.
The agricultural sector activity is one of the most important for the world economy, responsible for supplying demands in a multitude of areas, directly or indirectly, as far as human consumption is concerned. Tractors, for being very versatile, are used as one of the main tools in this environment, enabling the gain of strength and speed in the execution of work. Although tractors bring so many benefits to the agricultural environment, there are several precautions that must be strictly followed to preserve the life of the driver during the use of the machine. Many times, the work is performed on irregular soils, with many slopes and inclines, thus making the activity dangerous and propitiating accidents by lateral overturn, however, operating with tractors on sloping soils is considered pertinent in many situations. In a quick search, it is easy to find recent news about accidents involving tractor side overturns and considering that many of these cases are not accounted for by local authorities because they occur in remote regions, we conclude that the occurrence of these accidents is more frequent than it seems. With the advancement of regulatory norms regarding the safety of the individual when performing his or her activities, tractor manufacturers currently have a greater concern with worker safety, through the adaptation and development of safety systems that protect the driver during a tipping over. Nowadays the safety system that is mandatory, defined in Regulatory Norm 31 (NR31), is summarized in protection structures, in case of overturning, and safety belts, which do not prevent the accident, but can reduce its consequences. Considering all the aspects mentioned above, it is proposed to develop a system capable of preventing lateral tipping in agricultural tractors, thus reducing accidents with disabilities and/or fatalities through the Auxiliary Control of the steering system that enables steering when the risk of lateral overturn is identified in agricultural tractors, supported by simulations with Matlab and Siemens NX software.
