| Description: | Technical Report Abstract: This study concerns the effect of snow cover on the obstacle-crossing performance of over-snow tracked vehicles. Analyses of the performance of vehicles crossing vertical-walled steps and trenches were made based on obstacle geometry and vehicle characteristics and dimensions and were programmed for computer analysis. Obstacle-crossing field tests were conducted using the snow-trac and the M-29-C Weasel to obtain verification data. In areas of snow 2 to 3 ft deep the snow cover, along with snow transport and drifting, changed vertical-walled steps of over 5 ft into gently sloped, easily negotiable terrain features. Data were collected for vehicles crossing vertical-walled steps covered with up to 16 in. of shallow, soft snow. The agreement between predicted and measured negotiable step heights was good when vehicle and obstacle geometry, as well as vehicle sinkage and track deflection, were taken into account. |
