Abstract

fetched live from OpenAlex

PDF | Investigou-se o desgaste de mancais de rolamento axiais 51100, lubrificados, nacionais e chineses, associando-o à sua dissipação térmica, à sua energia elástica de vibração mecânica e acústica durante ensaios tribológicos acelerados em bancada de laboratório. Os corpos-de-prova foram adquiridos comercialmente e submetidos à carga normal de 450±5 N e à rotação de 3.100±30 RPM, estabelecidos após ensaios-piloto. Registraram-se as temperaturas [K] na zona a 3 mm do contato e a ambiente, a potência elétrica [W] demandada pelo motor, a velocidade de vibração global do sistema [mm/s] e o nível de pressão sonora NPS[dB]. As pistas, após ensaios de 106 ciclos, foram analisadas por Microscopia Óptica. Os rolamentos axiais chineses, de custo inferior aos nacionais, apresentaram respostas distintas em relação às dos nacionais. As assinaturas e a morfologia dos danos após os ensaios foram analisadas, enfatizando-se flutuações nas assinaturas do aquecimento das pistas, na vibração, na potência e no NPS.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
