| description | The article considers methods for studying torsional vibrations of the wheel-motor block of a diesel locomotive UZTE16M. The diesel locomotives in question were modernized at the structural enterprise “O’ztemiryo’lmashta’mir” (Machine building and repair in Uzbekistan Railways company) under the joint-stock company “O’zbekiston temir yo’llari” (Uzbekistan railways). The authors of the article developed a dynamic model for the analysis of torsional vibrational movements that occur in the traction transmissions of the UZTE16M diesel locomotive, taking into account the geometric dimensions of the electric traction motors of the main locomotives and the degree of their wear.
Based on the model of the wheel-motor block of mainline locomotives, differential equations of the torsional-vibrational motion of traction gears are obtained in the form of Lagrange equations of the 2nd kind. The results of numerical studies of the amplitudes of torsional vibrations of the wheel-motor block of the UzTE16M locomotive at different frequencies are presented. All calculations were performed in the MATHCAD 15 environment. |
