Mathematical Modeling Of Torsional Dynamics Of Wheelset Drive

The paper documents the results of mathematical modelling of the torsional dynamics of the partially and fully sprung individual wheelset drive in the simulation of the running of experimental bogie by in the mathematical model of the experimental roller stand ZCU, which was designed in experimental works of the CKDV. It presents partial results of the torsion dynamics of the drive of wheelset and the vertical dynamics of the experimental single-axle bogie, including the influence of the vertical unevenness of the rails and the torque fluctuations of the traction motor.
