Abstract

fetched live from OpenAlex

O desenvolvimento da indústria automobilística é fortemente influenciado pela expansão tecnológica, no qual se unem por meio de pesquisas, ensaios experimentais e procedimentos computacionais, que a cada dia estão mais precisos, dinâmicos e ágeis. A análise de resistência e desempenho de componentes mecânicos em projetos de veículos são de grande relevância para o setor, exemplificando os semieixos de caminhões. Este semieixo é responsável por transferir energia do diferencial para as rodas gerando a movimentação do veículo. Estes componentes estão continuamente sujeitos a carregamentos estáticos e dinâmicos passíveis de falhas podendo romper catastroficamente. Este trabalho tem como objetivo analisar o efeito da torção na resistência mecânica de semieixos utilizados em transmissão automotiva, aplicando o método de elementos finitos. As simulações foram realizadas utilizando o software ANSYS® Workbench 14.0, a fim de estudar o comportamento da peça quando submetido à torção. Os resultados obtidos na simulação numérica mostraram elevada concentração de tensão cisalhante no rebaixo das estrias do semieixo, coincidindo com a localização da fratura presente em um estudo de caso real.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
