GCr15/GCr15SiMn摩擦副在瞬时高应力启动过程中的静动摩擦转化特性
Transition Characteristics between Static and Kinetic Friction of GCr15/GCr15SiMn Friction Pair in Instantaneous High-stress Initiation Process
摘要
Abstract
To investigate the statictodynamic friction transition characteristics during instantaneous highstress startup,a test apparatus was constructed to simulate friction behavior under operating condi-tions.Experiments and simulations were conducted on a GCr15/GCr15SiMn friction pair,and the effects of contact stress and acceleration on the friction transition were examined.The results show that increasing contact stress causes significant plastic deformation of asperities,weakens the interlocking effect between them,and reduces both static and dynamic friction coefficients.Increasing acceleration enhances the asper-ity interlocking effect and raises the static friction coefficient,whereas the kinetic friction coefficient remains relatively unchanged.关键词
