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