Abstract

To investigate the static-to-dynamic friction transition characteristics during instantaneous high-stress startup, a test apparatus was constructed to simulate friction behavior under operating conditions. 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 asperity interlocking effect and raises the static friction coefficient, whereas the kinetic friction coefficient remains relatively unchanged.
