Friends and Solid Works Experts,

I have been trying to solve this problem since couple of days and i need some direction from you guys.

This is the bracket on which i am running a linear static study:

(Isometric View)

Front View

Given below is the schematic of assembly where this bracket is used:

Basically this bracket holds a part through 4 vacumm cups ( on one side) , the total mass of the part is 80 Kg and accelration forces are 270N acting horizontal through each of these 8 vacumm cups. ( I assumed that total mass is equally supported by all 8 cups hence 80/8=10Kg (100N) force acting through each cup)

I basically want to find out if the stress due to these forces are not causing the bracket weld to fail. ( Cause some of these brackets failed at our customer site)

I did a Linear Static Study and treated the forces acting through these 4 points as

"Remote Loads-Direct Transfer"and attached them to the highlighted face below because that is where the assembly holding the vacumm cups is attached to (See Schematic Sketch Below)Schematic Sketch of the whole Setup:
