Greg, it should be rigid mode which will participate more. But would I get any strain? My main problem is understanding strain from this, constant force produces strains, clear from Inertia relief analysis, but do I get strains from modal transient analysis in this case
How to understand the response from rigid body modes in modal transient analysis of free free aircraft model with landing gear loads. Does rigid modes respond to excitation part beyond 0 frequency?
Greg Locock thanks for reply. A freely falling body is in influence of field of gravity, so every small partical in the body has applied force which is equal to force on every other mass particle, so no particle pulls any other particle. But if situation is like a force at one end of rod with...
Hi members,
I have an issue in understating how modal transient analysis works free free structures. If I apply a time varying force with frequencies well above zero( say 40hz), and ask Nastran an FE solver to consider only flexible modes in analysis, the result is a mean zero response of...
