Space Shaker - Backstage Science

The Vibration Test facility at RAL Space allows scientists to simulate the rocky ride into space atop a rocket.

Includes test footage for the MIRI instrument.

I can't help imagining Mr. Bean siting on a table trying to have a cup of tea on top of that machine ^_^

I was waiting for the 20Hz moment when we can actually hear the movement of the platform.

that was flippen cool i think i want to break things on this now XD

[Yeahrrrrrr55]

this is a music instrument! at 4:52 it sounds exactly like a timpani!

@fossil98

It's actually quite similar in operation. It's driven by an amplifier, in this case I'd imagine it's close to 50kW. Two opposing liquid-cooled voice coils drive the shaker table back and forth.

That machine would do wonders in the chocolate claw games.

@pvskpraveen ya, i understand that text books say that, but what i assume is that there aren't a lot of scientists (not that im saying there arent any) that have been able to produce high enough spl possible for hearing these notes, i'm talking about hearing them in vehicles that are basically sound generating machines. i mean even at 155 you can barely hear that low. that much spl is very hard to produce even by bass competitors that have been around for years.

@pvskpraveen Recording hardware tolerances/limitations, probably.

Breaking items deliberately is blasphemy!

[pvskpraveen]

@lobstermendez thanks, I dont see any offence. But may be someone can explain why textbooks say 20Hz as lower limit when you were able to hear 14Hz...

[DontMockMySmock]

seems more like backstage engineering to me

@pvskpraveen i thumbed up your comment, so don't take this offensively, but i'm a car audio "basshead" and at high enough spl I have personally heard all the way down to 14hz, but we're talking about like 155 db or more.
