| Abstract: | The travel performances of off-road tires on pebble road were investigated with the three-dimensional discrete element model and finite element model (DEM-FEM). Numerical simulations were performed based on the established FEM of off-road tires, the DEM of pebble road and a special software ORV-SAND for off-road tire-granular sand interaction simulation. Travel performances of the off-road tires with different tread patterns, such as normal reaction, rim sinkage, gross traction, drawbar pull and running resistance were obtained under different slip ratios (10%, 20% and 30%), and compared with the related experiment results. |
