Abstract

In order to design the soil-recycling machine, it is necessary to understand the breaking performance for viscous clay. However, experimental investigation needs much costs and long experimental period. If the simulation model is developed, the effective and economical design will be possible. Therefore, in this study, the simulation model to estimate the breaking performance for viscous clay was developed by using DEM, and simulation result for size distribution of soil particles was compared with the experimental one. Simulation result was almost agreeable with experimental one. Therefore, it was confirmed that the simulation model developed in this study is almost reasonable.
