Abstract. Based on the theory of rigid bodies interaction with a contact moving point the formulation of the rolling wheel resistance along flat rail is studied. Taking into account the rheological properties of the contacting bodies material, the obtained inelastic resistance within interaction area of contacting bodies presented in the form of complex elastic modulus. The analytical dependences for determining the current value of resistance in the contact area is obtained. The energy loss during wheel skid in the contact area, friction coefficient while free rolling are calculated taking into account the physical and mechanical properties of the contacting surfaces. The relations of the motion resistance in dependence on on the contacting bodies and the track, physical and mechanical properties of the contact surfaces, as well as the determination of their numerical values allow evaluating the reserve of the tracktive effort and allow implementing the results.
Keywords: motion resistance, contact patch, stress, strain.
