- Abstract
- The tractive performance of a tracked carrier in deep snow was studied in parallel with conventional methods of snow property analysis in the region of Golden, British Columbia. Major sources of energy loss associated with vehicle flotation and development of drawbar pull were identified with the aid of running gear instrumentation and explained with the aid of penetrometers and excavation of deformed snow. The accounting for tractive energy loss suggests a means of gauging vehicle performance in snow and of classifying snow in terms of energy loss. The bevameter as an automated shear plate penetrometer in conjunction with elementary theory provides approximate predictions of drawbar pull. An instrumented reference vehicle may offer a viable alternative to the bevameter for predictions of trafficability.
