【 摘 要 】
In the study of vibroacoustic processes in mechanical gears of construction and road machines, one of their important tasks is to assess the compliance of the developed mathematical models with real objects. The article presents the methodology and theoretical dependencies for numerical methods for assessing the adequacy of the models of gears of mechanical transmissions of construction machines, which are linear oscillatory systems. The developed technique is based on the test effect of a single impulse perturbation on the model and the real object and comparing the spectra of their own oscillations. The results of theoretical and experimental studies of the primary shaft of a manual transmission of a medium-class earth-moving machinery are presented.
