Review article

In the operation of road transport equipment, an important role is played by its technical condition management. This aspect for power units operating in non-stationary modes is insufficiently studied. The purpose of this article is theoretical substantiation of the possibility of the correct application of vibration diagnostic methods for evaluating the technical condition of transmissions of transport-technological machines. The research was carried out on the basis of analytical mechanics provisions, spectral analysis, and mathematical modeling in specialized software environments. Generalized formulas for torque modeling are given. An equivalent model of the dynamic link of gearboxes has been compiled. It is recommended that the algorithms discussed in this article be introduced into the software of electronic control units for transport and technological machines, which will expand the hardware capabilities of diagnostic complexes of motor vehicles and improve the quality of management of their technical condition.
