The vacuum only needs to be drawn down a little bit -- our vehicles simply don't go that high. We have the pump, and the chamber just doesn't need to be that tight.

You can just as readily put a much smaller altitude chamber on the testing arm -- at the very least, at the end of the main centrifuge, with the smaller vibration generator inside it, but it shouldn't be hard to make a vacuum chamber robust enough (with remotely mounted vacuum pump and pressure regulator) to mount in the "hot seat" and thus need be only large enough to hold the component and test mount.On Mon, 18 Nov 2002 12:13:08 -0600, Rick Eversole <[EMAIL PROTECTED]> wrote:I-beam -> hammer/weight -> cam -> motor why that expensive ... sounds like something for junkyard wars ...That expensive, because you have to put it in an altitude chamber to completely simulate the environment and test the device.
Or do you feel you need to altitude test your vibration test fixture, too?
