Modificação do roteiro de exaustão de caminhões com motorização (230 Cv), para o roteiro de exaustão com motorização (190 Cv)

Abstract

The Brazilian vehicle trade has been overcoming a recent crisis and recovering gradually. Therefore, there is an increasing need for product optimization by companies, focusing on cost reduction, to remain competitive on business. Pre Development Engineering (PDE) is one of the areas that most contribute to this process. It contributes through the use of virtual analysis and modeling software on development propose, discarding unnecessary expenses with premature projects exercising a kind of validation before any physical test. Our project analyzed a case study in a large multinational company, in which besides a documental search, it demonstrates the importance of cost reduction to the company while exposes the key role that the PDE plays to achieve this objective. Tools as CAD (Computer Aided Design), CAE (Computer Aided Engineering) and CAM (Computer Aided Manufacturing) are essential to product development and their importance to the research will be emphasized, adding that FMEA and DFMEA analyzes were applied, tools of great importance due to the preventive direction that is given in relation to failures that may occur in the project in the future. Final results achieved were satisfactory through exhaust pipe line modification of Constellation 17.230 (230Hp) and 17.190 (190Cv) program, resulting in a R$49,56 cost reduction per unity of a multifunctional component and in addition it simplifies its assembling. Therefore, by the use of adequate analysis and modeling software, it was possible to improve and reduce costs in order to contribute to the increase of the company’s competitiveness in the market.
