- Abstract
- A concise vehicle mobility model is developed using quasi-static moving boundary displacement method. For a given condition of both tyre and terrain characteristics, the model calculates the contact length, the slip rate, the traction efficiency and the draw-par pull. The effect of tread configuration is also included in calculating the slip rate. To demonstrate the capability of the developed model, several examples are given. The results obtained by the present model are compared with the results from the previous finite element tread model (tread 85), which developed also at the Geotechnical Research Centre, McGill University. The results show that the new model is very promising.
