RESUMO

The alcohol produced in Brazil through the sugar cane is an alternative fuel that acquire her space on the world market with the interest of industrialized countries to contribute to reducing the planet pollution. In the process of ethanol production, there are several steps and one is the extraction of juice from sugar cane held, in majority, of the equipment called "milling housing". Knowing the behavior of this equipment efforts engaged in its structure is of paramount importance for the realization of these new projects and an optimization of existing ones. To the knowledge of these stress, technologies in the field of computer-aided engineering (CAE) bring computer programs (software) capable of fulfilling this purpose. Many software are responsible for an optimization in the process of product design, due to the fact that they are capable of detecting projects flaws with great ease, when something would be very difficult handling calculation. The objective of this work is to study the stresses working in the milling housing, the greatest expression throughout the suit of milling, to help in future projects and optimization of existing ones. To the knowledge of the stress working in the housing Cosmoworks, software for finite element that gives results with great accuracy, had been used. After the analysis, stresses working in the housing were presented with emphasis on the points of greatest stress concentration. The proof of factor of safety in the most diverse regions of the housing had been also explored. Based on the results presented, it is possible to optimize the milling housing reducing its own weight by 15% which is approximately 3,000 Kg. Knowledge of stresses in active components for the sector offers conditions to design new equipment optimized for an increasingly globalised market and thereafter more competitive.
