Experimental estimation of oscillatory parameters upgraded one-wheeled semitrailer
The Creation of new or modernization of well-proven samples of experimental stands and road installations always requires a preliminary calculation of their geometric and inertial parameters to ensure the necessary loading conditions of the test objects. But, after the implementation of such equipment in the metal necessarily requires a pilot test of its actual properties and characteristics. Therefore, after the modernization of the single-wheeled semitrailer of the Department of road transport, expressed in the suspension of the wheel with the test tire, its tests were carried out with full configuration in the mode of free oscillations with the involvement of equipment and devices of the bus stand SHS-77 to assess the main oscillatory parameters - the moment of inertia and reduced mass. The data obtained after the processing of the oscillograms allow testing pneumatic and airless tires in road conditions in loading conditions close to operational ones.
