FIELD: mechanical engineering; balancing facilities; evaluation of level of vibration and balancing of rotor systems in their supports and articles provided with rotary drives. SUBSTANCE: stand has base 1, table 2, resilient support 3, each provided with body 4, platform 5 and suspension of platform 5 made in form of leaf springs 6 installed square to platform 5 and spring dampers 7 to limit platform vibration amplitude. Lower ends of leaf springs are fastened on body 4 of support 3. Platform 5 is rigidly secure in middle portion of leaf springs 6. Upper ends of leaf springs 6 are fastened on crossmember 8 installed for self-alignment and axial displacement. Crossmember 8 is coupled with body 4 through resilient member 10 and screw-nut pair 11 for axial tensioning of leaf springs 6.
