Aiming at the internal relations between the abrasives layers of soft consolidation pneumatic wheel which consists of different material and the laser surface strengthening material removal rate,the DEM software PFC3 D was investigated. The model of the abrasives layer was established under the software PFC3 D and the internal relationship between the macromechanic and the material removal rate was gained.Then a compression test was taken on the Instron-5966 l tensile test machine and the simulation experim...
