On a separate note, there have been reports of aircraft wheels dropping off during landing or take-off. Does anyone know what are the likely causes...
I think the approach is to include as much modes as possible to best characterise the system response, but in practice, once the sum of the participation hits above 80%, it is good enough.

I am working on a random vibration FEA analysis of an electronic housing in Mechanica. I first ran a modal analysis to extract the modes (say first 40 modes), then ran a random vibration analysis with the input profile from 20HZ to 2000Hz, levels at 0.04 g2/Hz (typical workmanship input...
