FIELD: testing equipment. ^ SUBSTANCE: electro-mechanical stand for testing devices, registering parameters of movement of soil, caused by effect of seismic explosive waves includes body-frame with immoveable posts, on which moveable device table is positioned for devices being tested. Device also contains resilient support of device table and force exciter, consisting of electromagnetic force drive, anchor of which is connected to device table, and induction force drive. Electromagnetic force drive is positioned below device table on posts for holding force drives. Anchor of electromagnetic force drive can be used simultaneously by pusher of induction force drive. Anchor is mounted on supporting shoe, connected through resilient element to holding posts and positioned on acceleration disk of induction force drive. In acceleration disk and its guiding rod a through aperture is made with diameter not less than diameter of anchor of electromagnetic force drive. ^ EFFECT: extended range of reproduced movement parameters due to decreased mass of moveable parts of stand while maintaining conditions of operation for force drives and provision of comfort during setting up of devices being tested. ^ 1 dwg |
