Large-scale Separation Shock Test Facility

The separation shock test facility is used to measure and analyze the shock levels applied to a spacecraft when it separates from the launch vehicle and when the antenna is deployed in response to activated pyrotechnics, in simulated shock environments on ground.
The facility consists of a controller, an analyzer, high-speed cameras, etc. The pyrotechnic controller sends electric ignition current to the pyrotechnics to separate a spacecraft.The response data collected by the accelerometers mounted on a spacecraft are temporarily read into the data recording system, then uploaded in the analyzer for Fourier transform, shock response spectrum analysis, and other data processing. The photographic images of the state of separation are recorded by the high-speed cameras.
