Abstract
There was a need to install additional ventilation equipment with its takeaway on the workshop roof due to change of production schedules. The research showed that the change of a design scheme of bearing structures with organization of additional nodes which it leans on is the way for provision of safe work. This article is researching a dynamic load on bearing structures which is observed at working with additional ventilation equipment. The spectrum of natural frequencies of oscillations was determined. The values of these frequencies were compared with the frequency of forced oscillations of the equipment. The graphs of changes in the spectrum of natural frequencies are constructed when the fans reach the working frequency. According to the graphics, when the frequency of the driving force coincides with the frequency of natural oscillations, the inertial forces increase sharply which indicates the passage of the resonance zone. There was a research of change in dynamic forces due to rotor imbalance. A gap was found that occurs when bearings are worn which will lead to the destruction of the supporting element of the farm.
