Apply Bearing Load in Patran
Apply Bearing Load in Patran
(OP)
I need to learn how to apply a bearing load to a hole in Patran. I have the Force value (not pressure) and i need to apply this as a bearing load (sin function) to the hole in a specific radial direction. This is very easy in other software I have used, but I havn't found a good way to do it in Patran. I have geomerty entities as well as the mesh entities in the model so the force could be applied to either (whatever works better).





RE: Apply Bearing Load in Patran
You should make a cylindrical coord on the center of the hole. then you should define a vector spatial field with this function
-1* ( sinr ( 'T ) - abs ( sinr ( 'T ) ) ) / 2
defined on the cylindrical coord.
for the direction of load and 0 for the other directions.
apply a force on ALL node around the hole with as vector the field defined. and 1 on the Scale factor
run the utility Loads/BCs LBC Resultant to check for the total amount of load applied.
modify the load with a correct scale factor.
It's tricky but should work!!

If you prefer you can simplify it and use a spatial field with the function:
sin('T)
But you should pick only the grids in the front part else you will have a node with a pulling force!.

You mast apply the load in the radial direction, to do this you should define the VECTOR field only for the radial direction and not for the tangential.
I add an image of Patran with the field creation, maybe could help.

-1* ( sinr ( 'T ) + abs ( sinr ( 'T ) ) ) / 2.
BTW remeber to apply the load in the Cylindrical CSys (in my previous picture the coord 1008)
