MetaDAQ Tech-Talk at VIP 2011 Fürstenfeldbruck
In october 2011 we gave a technical talk about measurement and analysis of microvibrations on rotary machine at the VIP 2011.
The VIP (Virtuelle Instrumente in der Praxis) is National Instrument’s (NATI) largest european exhibition/congress.
In 2011 it took place in Fürstenfeldbruck near Munich.
Abstract:
Microvibrations on rotary machine may occure due to imbalance, axis misalignment, motor disturbances or ball bearing issues.
We described our solution (The MyVibSystem) to perform automated measurements, analysis and reporting on rotary machine.
The slides from our VIP 2011 presentation
Slide 1: motivation for automated microvibration measurements
Slide 2: Topics, overview
Slide 3: Spacewheels are used to compensate external forces on satellites in space
Slide 4: Principle of operation of spacewheels
It’s time for some educational fun now.
See the principle of operation of spacewheels demonstrated with three CD-players in micro gravity.
How does this work? Three spinning CD-players attached perpendiculary together will stabilize this „musical flightset demonstrator“ in space. This is accomplished by the gyroscopical forces induced by the spinning CD’s (It’s just physics law of conservation of angular momentum):
