Gravity(Acceleration) in simulation

Question asked by Pk M on Oct 29, 2013

Hi I would like to know if we have to apply gravity (acceleration) load for a lifing load simulation. The study I want do is for a overhead crane lifting bracket (stainless steel) for an equipment for "5g" load case. The weight of the equipment is 40lb. I applied 5g load (200 lb) as a remote load  at center of gravity(I am more used to Ansys where when I apply gravity, it used to show corresponding force acting upwards).

 

In solidworks simulation,as per help file, it looks like we dont have to give gravity. I just ran above 3 different studies to see affect of gravity - with Gravity UP, Gravity DOWN & No gravity. Interestingly all studies gave almost identical results. I couldn't make sense out of it. I would greatly appreciate if somebody could help me understand it.

 

Thanks,
