Study on the Running Resistance of Snow-Cars : 1st Report, On the Measurement of the Running Resistance of Caterpillar-Snow-Cars by Running Test

Abstract

The running resistance of snow-cars is much larger on snow covered surfaces than that of ordinary automobiles on hard ground surfaces. Consequently the value of the resistance has an important effect upon the running ability of snow cars. The writer investigated this problem, through running tests, by using the 16mm motion pictures and the engine boost pressures, especially making clear the effect of car velocity on the resistance.
