The article describes the choice of the design equivalent of the supporting devices of U-shaped frames of earthmoving vehicles. When calculating the U-shaped frames of earth-transport machines for the action of forces located in the plane of the frame, the supporting devices must be represented and calculated either as hinged-fixed supports or as a statically defined system. The difference in the choice of the calculated equivalent of the supporting devices leads to an is-total difference in the estimated load of the entire frame. Considering the same frame with the same load, but with different resistance devices, it is easy to reconcile that the value of the largest bending moment in the transverse part of the raw can vary by 30-35%. A significant difference in load exists in the longitudinal parts of the frame. In this regard, there is a need to formulate the criteria by which it can be concluded that the supporting frame device that is designed corresponds to the calculated equivalent. The correct choice of the calculated equivalent of the supporting devices of the ground-transport machine frame significantly affects the results obtained during calculations and helps to greatly simplify them.

“…However, the use of a quadratic form of are empirical coefficients, does not lead to a good result because recording one of the parameters, for example h, and obtaining good approximations in the range of large values of α and h, does not correspond to the physical phenomenon at small values of these parameters. The function Р(α,h) should give a rather close approximation in the range of values of the conducted experiment and meet the physical meaning in the range of extrapolation [12]. The following fourth-order polynomial meets these requirements:…”

The article presents the results of experimental studies of the ripping resistance force on a tracked bulldozer-ripper manufactured by the Chelyabinsk Tractor Plant. The experiment covers three ripping depths and eight angles. It has been experimentally established that the dependence of the ripping resistance force on each of these parameters is quadratic. The authors propose the use of a complex parameter which is equal to the product of the ripping depth by the angle when studying the ripping process. The use of the complex parameter for two-factor analysis allowed them to reduce the degree of the studied dependence while preserving the required accuracy. The complex parameter reflects the relationship between the design parameters of the ripper tooth, the ripping depth, and angle.
