Combined centrifugal and gyroscopic forces on a flywheel

Post by Westcliffe01 »

I am trying to develop a flywheel for an engine that develops peak power at 5800rpm and the vehicle that it is going into is capable of rotating around a vertical axis at a rate of 1hz. I have completed the centrifugal analysis with no problem. But apparently one cannot add a second centrifugal constraint.

So how does one go about simulating rotation about a vertical axis of an object spinning around a horizontal axis to get the combined effects ?

CalculiX allows for only one centrifugal load applied to a given set at a time. Thus, you can't simulate both effects in a single static analysis and you would have to run a dynamic study where rotation about both axes is explicitly simulated or (assuming full linearity) use superposition of the results of static analyses.
