Peter Rejto,Mario Taboadaod. The aim of analysing a large dataset is to derive statistically significant results on how angle of attack, speed, rail lubrication and rail grinding influence wheel squeal. The key finding is that the generation of severe wheel squeal is strongly determined by the angle of attack, which is cons作者: CULP 時(shí)間: 2025-3-23 12:28 作者: 中止 時(shí)間: 2025-3-23 16:36 作者: Dendritic-Cells 時(shí)間: 2025-3-23 19:11 作者: FILLY 時(shí)間: 2025-3-24 01:18
