Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Diagnosing of two the masses concentrated on a beam A.M. AHTYAMOV, A.R. AUPOVA (E-mail: aigul9@yandex.ru) A method that helps to diagnose the masses concentrated on a beam is offered, on two own frequencies vibrations. Mass of beam is taken into account thus. As changes of sizes of the masses can characterize the degree of wearing out of disks and sticking of foreign objects, so the found method allows to expose the necessity of repair of the proper mechanical system without sorting out. Key words: masses concentrated on a beam, own frequencies, vibrations.
