Effective mass and Inertia
Effective mass and Inertia
(OP)
Hi,
I have a simple question:
After I had realised a frequency analysis to calculate natural frequency of my model, I calculate effective mass and inertia. I just want to know what is the physical sense of these values. Moreover, if a mode has a very low effective mass and inertia, is it mean that I can don't consider this mode because it is not significant?
Thanks
Jérome

RE: Effective mass and Inertia
And I believe that : if a mode is near to the rotation frequency but it has a effectiv mass very low, it is not a problem because in reality, this mode will not be important.
Is it true?
