Applicability of Bekker's Expression to the Passability of Agricultural Vehicles

Abstract

There are two methods, W. E. S. method and Bekker's method, to describe the passability of the traffics. The former was established empirically by U. S. Army Corps of Engineers, Waterways Experiment Station, and the latter was established theoretically by M. G. Bekker, U. S. Army Ordnance Tank-Automotive Command, Land Lokomotion Laboratory. The author studied the applicablity of Bekker's method to the passability of agricultural vehiles and got the conclusion that Bekker's method could not be applied in the paddy fields in Japan.
