The main feature of modern earthmoving machines is the execution of a wide range of different operations. At the same time, the loading mode changes and it is characterized by coordinates, values of the applied forces acting on the machine and the regularities of their change in time. In order for the machine to be able to adapt to the listed variables, it must be equipped with the appropriate systems. Existing calculation methods do not allow taking into account the entire range of these effects. In the proposed work, adaptation approaches of earthmoving and transport vehicles to variable operating conditions are analyzed.

In the process of performing of technological operations motor-graders are undergone severe loading conditions. The process of working medium development is accompanied by the action of time-varying parameters reluctances on the working equipment. At the situation of operative bodies blocking which are accompanied by intensive vehicle braking loads on working equipment are of shock character and can exceed considerably neutral layer of usual loads. Such loading can lead to the crabbing of the vehicle from projected path of motion. The developed dynamic model of earth-moving machine allows to take into consideration dynamic loads effect on the path configuration of its motion and formulate prompts to stabilize the characteristic signs of earth-moving machine road-holding ability.

The article provides an analysis of the excitation conditions and the results of the detuning of parametric resonance in mechanical drive amphibious water-jet machines. The paper substantiates the possibility of solving the problem of reducing the dynamic load on the basis of the synthesis filter low-frequency vibrations.
