Re: g-load
Bill ,
Thanks for your answer. The structure is static. I do not have dynamic analysis capabilities. I need to see if the structure can sustain 4g load at static condition.
From your answer, I think, I can just apply 4 times the gravity load at the CG and I shoudl be good. right?

Re: g-load
Change your gravity constant to 4 times the norm. So 4*9.81m/s^2 = 39.24m/s^2.
I like Bill's answer better. Mine only works if your motion is opposite the direction of gravity.

Re: g-load
Thanks Dustin... the structure is static. It's not in motion.
So I just need to apply gravity load and put 4 in the verticle gravity ?

Re: g-load
That will work as long as your gravity force is applied in the same direction as the 4g loading on the real device. Just make sure you orient your analysis in the proper coordinate system and you will be okay.
Also, you won't input 4, you will input 4*9.81 m/s^2 or 4*32.2 ft/s^2
