| description | The article presents the results of a computational and experimental study of the dynamic loading of the transmission of a transport vehicle with an increased power diesel engine. The novelty of the study is substantiated in the scientifically based applicability of elastic torsion shafts between the engine and transmission as a torsional vibration damper, as well as in the development of a new experimental definition of the dynamic value of torque based on the principle of modulation of high-frequency oscillations of the signal of standard pulse speed sensors by modulating vibrations occurring in the power unit of the transport vehicle. As a result, the main calculated motor-frequency function of acceleration (torque) is obtained, including engine harmonics, harmonic components formed by the mechanisms of the connecting rod-piston and gas distribution mechanisms of the engine, the generator drive, vibrations in the transmission, etc. It is established that the reason for the limitation of the durability of torsion shafts is their operation in off-design modes due to the occurrence of a phenomenon called “task conflict”. On the basis of probabilistic calculations, a high comparative assessment of the probability of sudden fracture of elastic shafts at design and off-design loading modes is carried out. Based on the research results, a conclusion is made on the applicability of torsion shafts as dampers of torsional vibrations in the power unit with increased power. |
