Hi all! There are actual task to specialists. I have a problem. There is a platform. It made of aluminum 300x400x10 mm and must moving strictly along one axis (for example X axle). The Y and Z axis of this platform should be very tightly held. We can not allow fluctuations of Y and Z! Maximal shift along axis of the platform is 20 mm. Weight load on the platform no more than 6 kg. The platform must to vibrate along the axis with frequency from 0.5 to 1000 Hz. Question: is it possible to solve a similar problem using the platform which is sliding on the air gap? I want to giving up of all kinds of metal membranes, brackets, etc. Is it justified? Thank for attention!
