Thank you all for your reply.
electricpete, I am still not sure what you mean but thanks again.
unclesyd, I'll look into the thesis. Thank you very much.
Hello,
I have a question about calculating oil film stiffness and damping coefficients. From literature, it says that
Kxx = dFx/dx
Kxy = dFx/dy
Kyx = dFy/dx
Kyy = dFy/dy
Cxx = dFx/dxdot
Cxy = dFx/dydot
Cyx = dFy/dxdot
Cyy = dFy/dydot
My question is that if you have a limit cycle (journal...
Hello all,
I have a question about one small thing.
In literature, it says that linear analysis of hydrodynamic becomes nonlinear if the amplitude is larger than 40%. My question is how do you measure this amplitude?
Thanks for any replies!!
Thanks electricpete.
I am running a FEM simulations using COMSOL (FEMLAB). A thing is that even though I do not put an unbalance, when I look at the trasient journal motion, I get a periodic circle, not an equilibrium point. I thought I only get a periodic circle when I have an unbalance.
Hi,
I have a question about cascade plot. Cascade plot is usually for an imbalance rotors. Why is there a peak at 1x at low frequency?
Also is it possible to have 1x without imbalance?
