Estimating method of efficiency of wheel chassis driving on snow

[摘要] The method of an estimation of efficiency of a wheeled chassis during movement on snow is considered in the article. The change in snow parameters - height and density - during the winter period and the probability of a combination of these parameters is considered. Analytic dependences are given to calculate the height and density of the snow cover, depending on the duration of snow lying. An empirical coefficient is given allowing taking into account the increase in the spread of snow heights, depending on the duration of the winter. The concept of a criterion for the loss of mobility as a probability of the possible time of movement of the chassis during winter time without loss of passability has been introduced. A technique is proposed for estimating the mobility and efficiency of special chassis along the snow canvas of the track, taking into account variability of characteristics during the winter period.
