abstract

The results of linking research on analysis of the railway vehicle properties with the new designs of wheelsets, allowing various angular velocities of the tread rotations relative to the hubs by retaining gravitational-frictional torsional connection between them, are considered. Through an analysis of dynamic features during the hunting motion of the vehicle, carried out on the computer model using the nonlinear creep theories, the advantages of this design are found, which include first of all the decrease of wheel and rail wear, and improvement of dynamic features. The issue of metro car motion in the traction mode is specially considered. Tests on physical models and field tests of the tram and metro car verified the results received on numerical models.
