Abstract

Предметом изобретения является способ оценки твердости грунта, по которому передвигается транспортное средство, оснащенное по меньшей мере одним установленным узлом с радиальной жесткостью k, содержащим покрышку, имеющую корону, две боковины и два борта и оснащенную датчиком, чувствительным к окружной кривизне, который помещен вровень с короной, способ включает следующие этапы: оценивают значение кривизныпокрышки, соответствующее первым стационарным условиям покрышки в контакте с грунтом; оценивают относительную твердость грунта по отношению к радиальной жесткости kустановленного узла как функцию значения кривизныпокрышки.
