Abstract: A mathematical model for the traction, the lateral stability and the power characteristic was built based on the analysis and calculation of the snowshoving resistance, the tangential traction and the power consumption of a oneway plough type snowshovel. The snowshoving characteristic of the snowshovel of the DQX roadsurface snowplough was simulated by the proposed model using the software compiled by the authors. The simulation results show that the snowplough design meets the claims made by the project contract and the selected chassis matches well the requirements of the snowshoving of the DQX snowplough. The measured results in the snowshoving tests are in agreement with the simulated ones.
