3D non-equilibrium molecular dynamics simulations are performed to investigate the friction heat dissipation and generation of high-speed sliding system. A simulation model with two blocks is built. The different materials, velocities studied. mechanism at interface investigated. partition system obtained. results show that more will be produced higher velocity. But in case plastic deformation, less generated. mainly influenced by material velocity ratio. which has similar thermodynamic properties easier produce phonon spectrum.
