The article discusses relation of amplitude-frequency characteristics and transfer functions of electromechanical drive of rolling type wheeled mover. The paper defined overall transfer function considering impact of the phenomenon of formation of the contact surface and transfer functions under the perturbation and stress management. This allows the simulation and identifies energy efficiency as well as the parameters and characteristics of the onboard information-measuring system at the design stage.

The authors consider the relationship between kinematic parameters and energy properties of rolling wheel propulsor. The authors solve the problem of the existence of solutions for three-dimensional system "rolling wheel propulsor - bearing surface" when forming a bearing surface. The research also establishes the relationship between the speed of motion of the system and the nature of vibrations affecting ride comfort of a vehicle.

The article examines the influence of flat wheel movement in leading mode on formation of basic surface of movement. On the basis of the developed mathematical model the transfer function considering communication of output and input parameters, and also peak-frequency and phase-response characteristics of movement of the system wheel - supporting surface is defined. Work is executed within the limits of realization Scientific and pedagogical personnel of innovative Russia.

The article theoretically substantiates a possibility of self-excitation of oscillations of wheeled tractors frame in the longitudinal plane when working in traction mode. There was used the dependence of rolling pneumatic wheel radius from the vertical load and torque, mathematical model of a rolling pneumatic wheel with variable vertical load and dual-mass linear model of oscillations of the tractor frame in the longitudinal plane.
