Projeto e desenvolvimento de uma bancada de testes para freios inerciais de reboques

Abstract

This work was intended for the design and development of a test bench for trailer inertia brakes. To this end, bibliographic research was carried out in search of information about the different models of inertia brakes and their mode of operation, as well as their components, and a study and understanding of the standards NBR ISO 7643, NBR ISO 10966-8 and Annex 12 of the UN/ECE Standard. The test bench can be used for the inertia brake approval process, guaranteeing the trailer manufacturer a qualified supply to the market. The test bench must meet the aforementioned standards and allow the products (trailers with inertia brakes) to be submitted to product development and certification tests. The test bench was built in a virtual environment and simulated in infinite element software to ensure that it would support the load required for the tests. The structure supported a load of 700 kgf vertically and force values of around 2500 kgf horizontally, showing that it only needs reinforcement in one of its supports. Simultaneously to this process, a trailer was supplied, on which tests were carried out, in order to understand the standards and obtain data, in order to generate efficiency results.
