Resumo
A crescente demanda na aquisição de tratores agrícolas vem aumentando a concorrência entre os fabricantes e expondo a carência das empresas em produzir tratores agrícolas que possam atender as nececidades ergonômicas de pequenas e grandes propriedades rurais ampliando a opção do comprador com novos modelos que atendam às suas necessidades de uso. O lançamento de novos modelos de tratores agrícolas traz ao mercado nacional as mais recentes tecnologias ao posto de trabalho do operador de trator. A inserção de novas tecnologias na agricultura vem avançando constantemente em várias áreas, mas, especificamente no posto de trabalho do operador de trator agrícola, estas inovações não caminham na mesma velocidade, quando se utiliza de técnicas não tão atuais para avaliar com precisão o invólucro do operador de trator, dificultando, ainda, ao pesquisador a aquisição de equipamentos atualizados para a coleta de dados ergonômicos, principalmente para as coordenadas tridimensionais. Esta pesquisa teve como objetivo o desenvolvimento de um equipamento que possa coletar as coordenadas tridimensionais dos controles do posto de trabalho do operador de trator, automatizando a inserção dos dados diretamente ao computador e tendo maior precisão das medidas obtidas, eliminando os erros humanos de leitura e digitação. O equipamento proposto é composto de um sistema de angulação horizontal, vertical e um feixe de laser para medições diretas, sendo que os dados coletados por um módulo conversor da angulação, e um sistema de coleta sem fio para o feixe de laser. Com o propósito de coletar os dados, foi desenvolvido um programa computacional chamado de “Ergocoord”, na linguagem de programação Delphi. Para os dados coletados foram utilizados tratores novos com potência média de 74 kW, visando não alterar as variáveis da pesquisa...
The growing demand in the purchase of tractors is increasing competition between manufacturers and exposing the lack of companies to produce farm tractors that can meet the ergonomic nececidades large and small farms extending the option buyer with new models that meet their needs use. The launch of new models of tractors brings to the domestic market the latest technologies to the job of the operator of tractor. The introduction of new technologies in agriculture has been advancing steadily in many areas but specifically in the workplace of the operator of an agricultural tractor, these innovations do not go the same speed when using such techniques do not present to evaluate accurately the RTB tractor operator, making it also the researcher to acquire updated equipment for the collection of ergonomic data, especially for three-dimensional coordinates. This study aimed to develop a device that can collect three-dimensional coordinates of the controls of the job of the tractor operator by automating the data is entered directly into the computer and with higher accuracy of measurements obtained by eliminating human error in reading and typing. The proposed equipment consists of a system of horizontal angle, vertical, and a laser beam to direct measurements, and the data collected by a converter module of the angle, and a collection system for wireless laser beam. In order to collect the data, we developed a computer program called Ergocoord in the Delphi programming language. For the data collected were used tractors with new average power of 74 kW in order not to change the variables of the research. In the valuation of the proposed equipment used two methodological processes, the traditional method of measurement proposed by the NBR / NM / ISO 5353 - Road rollers, tractors and agricultural and forestry machinery - Point of reference of the seat, and adapted it standard...
