Given the rigorous conditions of high temperatures and diminished preload experienced by brake disc bolts in high-speed trains, this study conducted an experimental investigation into fatigue failure such bolts. Axial cycle tests were across five temperature levels four levels. This paper proposed a temperature-related regression model to characterize variation strength under temperature. The results indicated that bolt material decreases with increasing When increased from 20℃ 200℃ 650℃, decreased 29.7% 39.2%, respectively. life bolted joints correlated difference between force peak load. was reduced 17.8%, 30.8% 33.7%, when 200Nm 180Nm, 140Nm 40Nm,
