SEISMOSHOCK PROTECTIVE DEVICE Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: device is designed to protect radioelectronic equipment and other objects against seismic and vibration-shock effects of large amplitude and considerable duration transmitted through base in vertical and horizontal planes. It may also be used for protective against vibration-shock overloads during transportation and transfer of loads of up to 500 kg. The device consists of external and internal platforms secured by bearing rope over external platform perimeter. It is provided additionally with flexible adjusting members positioned horizontally in external platform corners and with damping ropes arranged on external platform in longitudinal and lateral directions, in horizontal plane under internal platform. Bearing rope is made as a contour consisting of turns of smaller-diameter rope passed through bushing holes of external and internal platforms. The device provides for higher degree of protection of radioelectronic equipment and other objects within low-frequency range and at effect of sign-variable impact loads of different form and duration transmitted through base. EFFECT: enhanced reliability. 2 dwg
