Ensaio Mecânico e Aplicação da Lógica Fuzzy para Avaliação do Canote do Garfo
(Universidade Federal do Pará, 2010) SANTOS, Ruy Sidney Nascimento dos; FARIA, Marlene Araújo de
Technological innovation has been one of the fundamental factors that drive major companies to stay atop the world ranking of the global market. Simulation methods for evaluating the mechanical behavior of products subjected to static and dynamic loads are extremely necessary to reduce manufacturing costs. This study aimed to use fuzzy logic in a product called the bicycle fork seatpost, where the degree of membership and accuracy, varying between 0 and 1, were analyzed, focusing on the product's behavior and its validation.

The study focuses on technological innovation in the industrial sector, using mechanical tests and computational simulations to evaluate the bicycle seatpost fork product. Impact and drop tests were conducted according to technical standards (NBR 14714:2001), with results showing 100% approval. Tools such as CAD, CAM, and CAE were essential to ensure product quality and durability.
Projeto e Execução de Ponte Extensionétrica para Medição de Deformação em Próteses de Membros Inferiores

The project developed an Extensometric Bridge to measure deformations in lower limb prostheses, using strain gauge sensors and a PIC microcontroller. The system converts voltage variations into deformations, displaying the data on an LCD and computer via RS232 serial communication. Simulations were performed in Proteus software, codes were developed in C, and a Delphi program was created for data visualization. The aim was to evaluate the behavior of prostheses under static and dynamic loading, contributing to the validation of their mechanical properties.
