METHOD OF DETERMINING COEFFICIENT OF SUMMARY RESISTANCE TO RUNNING FOR EVALUATION OF ROADS BY REALIZED PARAMETERS OF WHEELED AND CRAWLER VEHICLES TESTED ON ROADS

摘要

FIELD: vehicle testing. SUBSTANCE: to increase accuracy in determining coefficient of summary resistance to running and evaluating the roads at testing wheeled and crawler vehicles correction coefficient is used in dependence where K_j - correction coefficient; n - proportionally coefficient typical for each type of vehicle; - average fuel consumption l/100 kn on j-th - support surface; average running speed, km/h on j-th support surface. Novelty is that " value of coefficient of summary resistance to turning is corrected by coefficient accounting deviation of engine shaft speed of tested vehicle running over support surface at driving steady (discretely preset) or unsteady conditions relative to speed of engine shaft corresponding to conditions at which reference fuel consumption is determined and corresponding hourly fuel consumption at idle running. EFFECT: increased accuracy of testing. 4 cl, 2 dwg
