主 题:friction heat temperature field materials phase transition solid lubrication thermal-stress coupling analysis
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 *** temperature distribution of the bolt has been calculate with heat radiation and heat convection *** a solid lubricant,polytetrafluoroethylene (PTFE) has bee considered to reduce the friction heat *** result 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 *** PTFE lubricant has been applied,the temperature of the bolt joint increased to 260 ℃,and the bolt steel can by applied in this *** results provide important guidance for the bolt structure modification and material selection.
