Arranjo fisico na montagem com fluxo continuo nas superficies de comando composto

Based on the fierce competitiveness of manufacturing companies and the planning problems arising from the lack of flexibility and forecasting demand, companies are increasingly looking to reflect on the most appropriate methods to manage its manufacture. Today it is possible to obtain higher gains and lower costs through very efficient tools, this paper uses action-research to model and implement the physical layout of a manufacturing cell, with strong theoretical basement returned to Lean Production System and acting systematically in flexibility in mounting. Through observation and joint action of the observer and staff can report problems that occurred during the phases of planning and implementation of improvements. With the improvement of the physical arrangement in the assembly was possible to obtain significant gains by reducing the production cycle, the manpower required, spending of non-compliance and increasing productivity, final product quality and health in the workplace

Blade design and forming for fans using finite elements

The necessity of adapting the standardized fan models to conditions of higher temperature has emerged due to the growth of concerning referring to the consequences of the gas expelling after the Mont Blanc tunnel accident in Italy and France, where even though, with 100 fans in operation, 41 people died. However, since then, the defied solutions have pointed to aerodynamic disadvantages or have seemed nonappropriate in these conditions. The objective of this work is to present an alternative to the market standard fans considering a new technology in constructing blades. This new technology introduces the use of the stainless steel AISI 409 due to its good adaptation to temperatures higher than 400°C, particularly exposed to temperatures of gas exhaust from tunnels in fire situation. Furthermore, it presents a very good resistance to corrosion and posterior welding and pressing, due to its alloyed elements. The innovation is centered in the process of a deep drawing of metallic shells and posterior welding, in order to keep the ideal aerodynamic superficies for the fan ideal performance. On the other hand, the finite element method, through the elasto-plastic software COSMOS permitted the verification of the thickness and structural stability of the blade in relation to the aerodynamic efforts established in the project. In addition, it is not advisable the fabrication of blades with variable localized thickness not even, non-uniform ones, due to the verified concentration of tensions and the difficulties observed in the forming. In this way, this study recommends the construction of blades with uniform variations of thickness. © 2007 Springer.
