The paper focuses on a method for assessing the dynamic loading of the frame of a special wheeled chassis when it moves on roads of various categories. Based on the developed finite element model of the frame, we obtained and analyzed full-size patterns of the stress-strain state of the frame and oscillograms of equivalent stresses in the most loaded zones of the frame.

The purpose of the study was to analyze the basic technological process of manufacturing waveguide flanges at PJSC “ALMAZ R&P Corp.” LEMZ Division. A method for optimizing the process has been proposed, and a theoretical study using the finite element method has been carried out. The stress-strain state of the forging of a complex shaped flange during its manufacture with closed bulk forming has been analyzed as well.
