Vibration-induced friction temperature field analysis under different working condition of heavy load bolt

摘要：

Based on thermal-stress coupling analysis and material properties studies, the vibration-induced friction process of a special used heavy-load bolt has been simulated. The temperature distribution of the bolt has been calculate with heat radiation and heat convection considered. Also a solid lubricant, polytetrafluoroethylene (PTFE) has bee considered to reduce the friction heat effect. The resault shows that, there are very strong heat effect while no lubracant considered, the temperature of the bolt joint increased sharply and up to 700℃, which exceed the allowable temperature range of the steel. When PTFE lubricant has been applied, the temperature of the bolt joint increased to 260 ℃, and the bolt steel can by applied in this satuation. These results provide important guidance for the bolt structure modification and material selecion.
