Projeto e simulação computacional de uma bancada de ensaios de impacto e queda em quadros e grafos de bicicletas

Abstract

The present work aims at the development of a bench of tests for frames and forks of bicycles, with the purpose of being another bench of conformity tests to test like bicycles produced in our region (Teresina and North-Northeast). Firstly, bibliographical surveys were carried out on impact and fall tests on bicycle frames and forks so that the project could be seen in its entirety, and then determine its characteristics, materials, limitations and restrictions of the bench, for control or purpose successfully. It was then established that the bench has a simple design, low cost and easy to handle, in addition to both tests are performed in a single structure. Based on these early design steps, project sketches and drawings were sketched through analysis to detect positive and negative points. In other words, make several inter-urban comparisons to a detailed final project (2D and 3D). After that, the materials and a methodology of the construction are determined. With the revised project, the same went to the stage of computational validation, that is, simulations were carried out outlining the efforts that the bench undergoes during the tests, after the positive results, the next step to the beginning of the construction process. One of the most important points in the implementation of the laboratory bench in the city of Teresina is that the local industry and the consumer market for bicycles are the most benefited, since they generate less expenses for the industry, and the final product will have more reliability for the consumers. On the other hand, a bench will bring many more to the industrial two-wheeler sector, providing greater consumer safety and will
