RESUMO

This thesis describes the reorganization of a bus chassis family through the modular analysis. The reference of this analysis was a chassis already in production. As a first step, it is important to identify the needs and features of the engine and the peripheral components for the creation of the model which allows us to develop new engine peripheral components derived from the reference chassis. Analyzing the state of the art of the modularity, it was possible to apply techniques, methods and tools for grouping the modules, interface identification, modularity measurement and impact evaluation on the modules due to new modules development or boundary condition adjustments. The result is the development of new engine peripherical components with high degree of standardization of the modules, components and systems. The consequences of the standardization of the product architectures to the project are the development time reduction and higher reliability of the project. The origin of this work started due to the necessity that the auto-industry plants have to in order to adapt their vehicle variants for each new emission legislation. In the last years, the environment started to be the center of attention, reflecting in more challenging emission legislation, each time more restrict in relation to the emissions of gases to the atmosphere. The unfulfillment of the legislations would produce the effect of market loss and consequently profit reduction. In this scenario, the engine and peripheral components start to have a special attention, because it will depend on them to fulfill the emission limits. The goal of this work is to redesign the engine periphery by means of a feasible model based on modularization and which produced satisfactory results
