Seismic protection Vibration-isolation system for an autonomous power supply unit.
Client and task
A departmental enterprise approached us with a request for a seismic protection system for an autonomous power supply unit weighing 1,000 kg, designed to withstand a seismic impact of 9 points on the MSK-64 scale.
Solution
We designed a two-level vibration-isolating platform based on two types of cable vibration isolators. Our partners conducted dynamic and strength calculations using the finite element software ANSYS to verify the solution.
Result
Testing showed that the platform effectively protects the autonomous power supply unit from seismic shock impacts with an acceleration amplitude of 200 m/s² and half-wave durations of 30–50 ms, in accordance with GOST RВ 20.39.304–98 requirements for equipment group 1.2.3.
In the photo — a "mock-up" of the platform: we checked the design, then designed and manufactured a similar platform for the same enterprise for a power supply unit weighing 1,700 kg.Additional photos
