apply a load to hollow part

ElineH

Hi,

 

I am optimizing an aircraft engine bracket (see image) and I would like to apply a (one horizontal and one vertical) load to the upper openings (indicated).

It is a point load that should be applied to the middle of these openings since there is some kind of bolt carrying the load in real life. Applying a load to the centre of the opening and so 'air' obviously is impossible. Anyone any idea how to apply the load or linkt the centre of the opening to the structure?

 

thank you!

Hi,

 

it is common practice to create a rigid (RBE2) spider and apply the load to the independent node. 

In general, it is best not to apply loads and displacements directly to design spaces, as this often leads to incorrect results. Instead, you should split the part into design and non-design spaces, and apply loads and displacements to the non-design spaces.
