STAND FOR MODELLING SEISMIC EFFECT OF EARTHQUAKE ON STRUCTURE MODEL Russian patent published in 1994 - IPC

FIELD: training laboratory plants. SUBSTANCE: stand consists of base with frame secured to base posts by means of link-turning mechanism having retainer. Rigidly connected to frame is impact mechanism with drive and seismic platform provided with shock-absorbing system and working table attached to seismic platform also by means of link-turning mechanism and retainer. Installed on table are transducers and tested objects.
