Abstract

In the article presented the parameters of the softening pad, i.e., its width, angle of entry into the soil, radius of curvature and aggregate movement speed, level of soil compaction, the height of unevenness formed at the bottom of the softened layer, and the height of unevenness formed at the bottom of the softened layer, are at the level of agrotechnical requirements. Multifactorial experiments were conducted according to the Hartley-4 plan. In this case, the level of soil compaction, i.e., the amount of fractions smaller than 50 mm in size, the height of irregularities formed at the bottom of the softened layer, and the tensile strength of the softening pad were taken as evaluation criteria. The data obtained in the experiments were processed by the "PLANEXP" program developed in the experimental-testing department of RIAM, and regression equations were obtained that adequately represent the evaluation criteria. In this case, Cochran's criterion was used to evaluate the uniformity of variance, Student's criterion was used to evaluate the value of regression coefficients, and Fisher's criterion was used to evaluate the adequacy of regression models. The obtained regression equations are the degree of soil compaction, that is, the amount of fractions smaller than 50 mm in sizeNot less than 80 percent, the height of irregularities formed at the bottom of the softened layer not more than 2 cmand the optimal values ​​of the parameters were determined by jointly solving the conditions of the minimum value of the tensile strength of the softener pawl
