Desenvolvimento de um sistema alternativo de fixação de poltronas junto a lateral da carroceria de ônibus rodoviário

Abstract

The present work has the objective of developing an alternative system for fixing the seats of the Marcopolo buses, along the side of the body structure. In order to comply with this, design techniques such as the DFM, DFA and DFMA were studied and analyzed, as well as the observation of technical standards and regulations that apply to the anchorages of the seats of this category of vehicles. In the development of this work, fixation proposals were created, which were initially analyzed through the finite element method to arrive at a final project and to apply the 3 point belt test. The test did not achieve the expected results, since a lateral fixing part failed. However, comparisons were made with the current system employed in the company and were perceived, for the developed proposal, advantages of structural weight, component standardization, assembly time reduced by approximately 54%, ergonomics and cost with 5% reduction (sic).
